1 The Danish Polymer Centre 1999/2000
This report covers the main activities in The Danish polymer Centre in the period starting July 1 st
1999 to December 31st 2000. Section describes in a short version the activities, more details are
found in the following sections.
1.1 Introduction
The Danish Polymer Centre is based on collaboration between the Technical University of
Denmark and Risø National Laboratory with significant support from the Danish Science
Councils and Danish industry. The goal is to contribute to the competitive edge of the Danish
polymer utilising industry by means of activities within research, development, and education.
The Danish Polymer Centre was inaugurated in October 1999 based on a collaboration
agreement signed March 1999. The Department of Chemical Engineering and the Department of
Production and Management at the Technical University of Denmark, together with the Risø
National Laboratory, provide the core of the Danish Polymer Centre. The purpose is to create an
efficient research and training environment in close cooperation with other public research
institutions and with Danish industry.
The Polymer Centre has some 60 staff, and is financed by support from the Risø National
Laboratory, the Technical University of Denmark and the Danish Research Agency (STVF). It
also receives grants from the EU, and funds from a range of industrial enterprises and other
private sources. It is worthy of particular mention that Aage and Johanne Louis-Hansen's Fund
has donated a five-year research professorship to the Centre.
1.2 Research
Despite the fact that the first period of the centre’s existence has involved many transitional
activities, significant scientific results have been obtained. A measure of this activity is the
number of international publications (more than 75 papers/year) obtained by the centre staff. A
few examples of ongoing research are given below.
The centre has continued activities in the numerical analysis of the flow and deformation of
polymer melts. As a result a full 3D flow simulation program for time dependent free surface
flow of viscoelastic polymeric fluids has been implemented. Based on a Lagrangian finite
element method, the program provides the first and so far only tool to analyse complex free
surface flows of polymer melts (J. Non-Newtonian Fluid Mech. 92 (2000) 227-243). It has a key
role in the design and development of new equipment for the rheological characterization of
polymer melts in elongation likewise developed in the centre.
Ordering and gelation phenomena in polymer systems have been a subject of the groups in the
Polymer Centre for long time. In solutions of star-polymers, experiments of structure and
rheology have revealed the so-called 'jamming' transition, as proposed theoretically for soft
interacting systems (Phys.Rev.Lett.85, 4072, 2000). The thermodynamics of 'Lifshitz critical
behaviour' have been studied in ternary model-systems of PEP and PDMS homopolymers and
the corresponding block copolymer PEP-PDMS. The ternary mixture shows near the boundary
Page 3

etween lamellar microphase separation and true two-phase separated systems remarkably
renormalized characteristics, including a micro emulsion channel between the two phases
(Phys.Rev.Lett 82, 1756, 1999; J.Chem.Phys. 112, 5454, 2000).
A number of studies have concerned polymers for electronics applications, including structural
studies of poly-(dodecyl-bithiophene) films (Nature, 401, 685 (1999)). It has been shown that
through the film-production procedure, it is possibly to get a high degree of control on the
crystalline texture and alignment. The studies of poly-(dodecyl-bithiophene) include also the
ordering phenomena in solutions prior to film formation.
A variety of important results have been obtained in the polymer actuator project. The studies
include the possibility to base the actuator on a composite material comprising one conjugated
polymer capable of changing oxidation-state upon the onset of an electrical or chemical stimulus,
and an ion-sensitive gel capable of changing volume (applied for patent). Actuators based on a
special acrylate polymer have been proven to have excellent performance: with a length of 10 cm
and a cross-section of 5x5 mm, weighing just 4 g, such a prototype actuator were able to lift 1.5
kg more than 8 mm.
More details of the scientific activities and results are given in the Research Activity Report.
A list of publications is found at the end of the report.
The Danish Polymer Centre have been involved in the organization of conferences and
workshops, including ’Polymer Surfactants’ (Kolle-Kolle, Denmark 24-28 June 2000); and
’EPS-CMD18 Conference, Colloquium on Transient phenomena in complex systems', (Montreux,
Switzerland, March (2000)).
1.3 National and international collaboration (Academic)
National Collaboration include:
The Royal Veterinary and Agricultural University; CISMI Copenhagen University; University of
Aarhus; University of Aalborg; Roskilde University Centre; Other DTU and Risø Departments.
The Polymercentre has close collaboration via a joint ph.d. project with Department op
Chemistry, University of Aarhus. This project is finansed by the Polymercentre. A similar
arrangement is planned with University of Aalborg, but it awaits quallified candidates. Likewise,
the centre has joint projects with other departments at DTU and Risø, where the centre cofinanses
a ph.d. project (functional polymers) and a guest professor within biopolymer/biofiber
composites.

’EPS-CMD18 Conference, Colloquium on Transient phenomena in complex systems', (Montreux,
Switzerland, March (2000)).
1.4 Education
An educational board was established in 1999. In 2000 the board finalized a proposal for a
coherent structure of the polymer courses at the DTU. The aim has been to develop a coordinated
and attractive range of courses, which will allow students to select optimal combinations ranging
from polymer chemistry to polymer processing. Moreover, a significant effort has been put into
the redefinition of the polymer engineer line at the ‘Diploma’ studies. The proposal includes the
development of two large introductory polymer courses that combine theory and laboratory
work. The proposal was submitted in 2000 to the Department of Manufacturing Engineering and
Management (IPL) and the Department of Chemical Engineering (KT).
Three summer schools within polymer science have been conducted with participation of the
Danish Polymer Centre.
Several polymer candidates have graduated in the period. A list of names, project titles, dates
and the relevant departments is given in section 3: Educational activities.
1.5 Industrial collaboration
In 1999/2000 the Polymer Centre hosted several contact meetings with Danish polymer utilising
companies. On the basis of these contacts the Polymer Centre has been involved in creating two
research consortia directed towards polymer degradation and polymer joining. The polymer
degradation consortium (MONEPOL) applied for and was granted a 3-year centre contract
‘Centerkontrakt’ by the end of 2000. In addition, the centre collaborates with a larger number of
Danish companies via two existing centre contracts ‘Centerkontrakter’ – COMF and HYDECO.
An EU contract on the development of new biopolymers for food packaging was selected for
granting. The consortium, which includes two Danish companies and The Royal Veterinary and
Agricultural University (KVL), is expected to sign final collaboration contract early 2001.
In addition the Polymer Centre took part in bilateral collaborations with several Danish and
foreign companies. These include Borealis A/S, Coloplast A/S, Danfoss A/S, Maersk Medical
A/S, Mallinckrodt A/S, Medicotest A/S, Novo Nordisk A/S, Novozymes A/S, NKT Research
A/S, Radiometer A/S, and Roblon A/S.
In total, the Danish Polymer Centre has collaboration with more than 20 Danish and international
companies.

1.6 Personnel
A list of personnel of the centre is given at the end of the report. Within the core activities, two
academic staff members and two new Ph.D. students were employed in 1999. In 2000 the new
research professor (Søren Hvilsted) was appointed, one new staff scientist and four new PhD
candidates were employed.
In 2000 a management and personnel development programme was initiated. The reason was to
strengthen the collaboration between staff members from the two institutions, to establish joint
values and to use these values in the daily organisation of the centre. Support for this project was
obtained from the so-called ‘Omstillingsfonden’ with the Ministry of Finance. The project will
be concluded with an evaluation in the summer 2001, until now, it has been a successful process.

1.8 New facilities
The design of the new laboratories at DTU was planned in 1999. This work created the basis for
obtaining the official approval from the Ministry of Research to start up the building project for
building 423, which was finished on schedule around new-year 2000. About 500 sqm. of
excellent laboratories with adjoining office space were established on the two top floors of the
building.
The process laboratories in building 427 at DTU will be moved and expanded to give room for
new activities. This work started late 1999, and the first process hall was finished early 2000. A
clean room facility for microinjection moulding was finished in the summer of 2000.
At RISØ the process of concentrating the activities in building 111 has started in 2000. Some
activities have been moved to DTU. The first Small-angle x-ray scattering facility was
established at Risø.
The main part of the investments in large equipment was done in 1999 and 2000, but a
significant fraction of the investments await new laboratories early 2001.
1.9 Economy
In general, the economy of the centre follows the general budget as set within the grant
conditions. The turnover of the centre fall within 4 more or less equal sized parts from the main
grant (STVF), DTU, Risø, and externally financed projects, respectively.
The economy of the main projects, funded by the science councils (STVF) are proceeding well.
The investments are a little behind schedule (20%) awaiting the start-up in our new building at
DTU. The delay will be caught up with early 2001, via planned investments. Also the salary
expenses are slightly lower than the budget (10-15%), due to delayed start-up of PhD projects.
This will be compensated by a somewhat higher activity by the end of the first 4-year period.
The main partner institutions are co-funding the activities via staff salary, running costs,
investments and building costs. In addition, the centre has obtained significant support from
external sources, including other science council project, EU grants, ‘centre contracts’, industrial
sponsorships, industry projects etc.
1.10 Summary and outlook
During the fist 18 months of the existence of The Danish Polymer Centre a large number of
projects have been started and the first results have been obtained. In 2000 the centre produced
more than 75 international publications, a new plan for the polymer education have been
presented to the involved departments, and a number of new industrial projects have been
started. The new building for the activities at DTU was completed December 2000. The accounts
are slightly below the budget.

In 2001, The Polymer Centre will maintain the research quality and expand the activities within
our focus areas. Special effort will be given to strengthening the activities within polymer
processing. Also, the national and international network within polymer research and education
will be given emphasis. The visibility of the centre on national and international scale can be
improved, and the centre will market itself as an attractive research environment, a good place to
study and the obvious partner for industry related projects concerning polymer materials and
processes.
The centre is in good progress and it is expected to grow steadily over the coming years. An
international evaluation of the centre is foreseen early 2002. It is the ambition of the centre that
this evaluation should be excellent and that it will pave the way for a continued support for a
permanent Danish Polymer Centre.

2 Research
The research projects are described below concentrated towards progress within four designated
focus areas as listed below. In addition one project has been initiated within the area of polymer
composites. Finally the Polymer Centre runs several projects that are not within the focus areas,
but still within the general area of polymer science and technology. These projects, denoted
external projects, are listed in section 2.6 below.
2.1 Focus area: New Polymer Materials
The synthesis of materials with new and well-defined properties is interesting and important for
future breakthroughs and applications. Theoretical modelling of the interplay between molecular
structure and functional properties will give valuable input for the design of novel materials.
Specially synthesised model polymers are important for the investigation of predicted or
anticipated relations of structure and properties, and a pilot-scale production line will be
established to meet such demands.
The following projects have been started in this area:
Controlled free radical polymerisation of monomers with specific functionalities for new
applications. ( Jørgen Kops).
The goal is to be able to utilise controlled/”living” radical polymerisation for the synthesis of
designed polymer structures such as block and graft copolymers to obtain specific properties.
Thermo- and pH-responsive amphiphilic polymers with induced phase changes are being studied
for possible use in reversible micellar and gel formation applications. Ph.D. student Jens Høg
Truelsen is funded within the project.
Molecular tension sensors for polymers. (Mikkel Jørgensen).
The goal of this project is to prepare molecular tension sensors which translate a molecular level
tension to an optical signal through a change of the sensor conformation and orientation.
Mapping of the local tension in polymer objects can then be obtained through a microscopy scan.
Organic synthesis is used to prepare active units that change their optical properties (absorption
or fluorescence) in response to changes in geometry. These units are then linked to polymers of
interest using e.g. anionic polymerisation techniques.
Test samples are then characterised spectroscopically using absorption and fluorescence
spectroscopy. Both in relaxed and stressed conditions.
Synthesis of a few tension sensor units has been carried out. Characterisation is under way.
Incorporation into polymers is also progressing. Spectroscopic characterisation is pending the
delivery of a new fluorescence spectroscopy instrument. Ph.D. student Holger Spanggaard is
funded within the project.

Polymer Electrochemistry (Keld West).
The purpose is to prepare and characterise electro active polymers, e.g. ionically or electronically
conducting polymers. The main focus is switchable materials that can respond to an electric
stimulus by changing one of their physical characteristics.
Optical properties of organic materials. (Per Michael Johansen).
This project is aimed at studying the reorientation dynamics of rod-like dipoles in a polymer
matrix. Studies of the polarization kinetics of small rod-like dipoles imbedded in a polymer
matrix yield important insights into the mesoscopic structure of such systems. The model system
currently studied consists of a PMMA polymer matrix in which chromophores of Disperse Red 1
is either in a solution or fixed to the polymer as a side-chain. The dynamics of the system are
investigated experimentally by studying the optical birefringence as a function of both dc and ac
electric fields applied to the sample. Theoretically the response is modelled using the rotationaldiffusion
equation (Smoluchowski equation) and detailed comparisons between the two are made
to obtain the material parameters for the electro-optic response. Ph.D. student Kim G. Jespersen
is co-funded within the project.
Functional Block Copolymers. (Søren Hvilsted).
The project aims at the development of new well-defined functional materials by use of new
strategies and controllable polymerisation techniques. One goal is to implement a general
approach that allows us to produce amphiphilic materials where one part has a strong adherence
to hydrophobic polymer surfaces whereas the other part retains hydrophilicity or even water
solubility. Another goal is the ability to phase engineer materials that response to external
stimuli, e.g. light, in a controlled manner.
This project is funded by the generous grant from Aage and Johanne Louis-Hansen foundation.
2.2 Focus area: Polymer Blends and Networks
Multi-component systems are essential in polymer applications, and include polymer blends and
colloids. Complex morphologies can be obtained and controlled by clever molecular design and
modification of interfaces, which open new applications for polymers in nano-technology. Crosslinking
of polymer systems is another way of changing the material properties and creating new
materials via the formation of networks. Studies of structure and dynamics are necessary to
better understand the properties of such materials.
The following specific projects have been started in this area:
Synthesis, characterisation and structure of block copolymers. (Kristoffer Almdal).
The project aims at synthesising and characterising model block copolymers. These include
polymers containing a random distribution of relatively short block of polymers A and B - where
A and B occur in random order. Furthermore high molar mass poly(dimethylsiloxanes) (PDMS)
with narrow molar mass distribution and possibly end functionalisation amphiphilic block
copolymer where one part is an electrolyte are included. On the outset this project was planned
to involve a Ph.D. student. However, so far fund and a suitable candidate have not been attracted.

Diffusion of small molecules in polymers. (Peter Ogilby, Aarhus University).
The aim of the project is to explore issues related to diffusion of small penetrants in polymers.
These issues are the acquisition of accurate diffusion coefficients, the mechanism of small
penetrant diffusion in heterogeneous polymers and the diffusion-dependent mechanisms of
degradation of polymers. Diffusion of oxygen, water and carbon dioxide in glassy polymers will
be monitored by spectroscopic techniques: Singlet oxygen phosphorescence and step-scan FTIR.
Confocal Raman and IR microscopy will be used to monitor diffusion locally and across
boundaries. New polymer materials like poly(ethylene 2,6-naphthalate) (PEN) and a cyclo-olefin
copolymer (TOPAS) will be characterised. Ph.D. student Lars Poulsen (AU) is funded within the
project.
Selective adsorption from Polymer Blends to solid Surfaces during flow. (Jørgen Lyngaae-
Jørgensen).
The objective with this project is to examine/predict the development of surface morphology of
immiscible polymer blends during flow against high energy surfaces. Specifically a hypothesis
for the critical condition for transition from a polymer A film to a polymer B film when a welldispersed
blend of A and B is subjected to a simple shear flow under steady state conditions has
been tested (positive).
2.3 Focus area: Structural Development of Polymer Melts at Processing Conditions
Processing of polymers span a range of mechanical deformations (e.g. shear strain and
extensional flow). This has a dramatic impact on structure, and in order to understand and utilise
the effects of strains and flows, the influence of processing on material properties can be studies
by in-situ x-ray, neutron, or light scattering techniques as well as transmission electron
microscopy for the direct imaging of morphology.
An in-situ structural study of thermoplastic elastomers during processing
(Erik Kjær, Kell Mortensen and Martin Vigild).
Polymer melts change their orientational order under the influence of shear flow. This
phenomenon can be utilised in functional materials. To do this requires an understanding of the
physical and chemical basis that governs these effects. Such knowledge will lead the way for an
efficient nanostructural engineering approach to improved properties of polymer materials. In
order to study the effect of processing polymers it is essential to have techniques for real-time
collection of data that enables a direct correlation of processing conditions to material
characteristics such as texture alignment, molecular conformation and structural relaxation
processes.
This project focuses on building an on-line birefringence experiment mounted on a Reometrics
Solids Analyser RSA ll. The two folded aim is i) to make time resolved birefringence
measurements at a single point, thereby monitoring transient phenomena which exist during
processing, and ii) to make 2D visualizations of flow patterns occurring at process conditions.
Ph.D. student Rüya Eskimergen is funded within the project.

Characterization of polymer melts in elongation. (Ole Hassager).
The goal of this project is to understand the development of structure, molecular orientation and
stresses in polymeric melts under elongation. It is desired to understand how the ability of
polymers to form fibres is influenced by structural factors such as long chain branching.
Molecular theories suggest that the elongational viscosity is particularly sensitive to branching.
Hence the ultimate hope is to be able to construct an apparatus by which chain branching and
other structural characteristics may be measured. Ph.D. student Anders Bach is funded within the
project.
Tailoring of Bicontinuous Phase Structure (BPS) During Processing. (Jørgen Lyngaae-
Jørgensen).
The objective is to govern/predict the formation of bicontinuous phase structures in two phase
systems during flow in the whole volume fraction interval.
Structure and Properties of Materials with Microporous Structure. (Jørgen Lyngaae-
Jørgensen).
The objective of this project is to prepare micro porous foams with a controlled/tailored
microstructure, and to demonstrate the influence on the structural and micro mechanical
properties. Carbon foams are of interest because they have good engineering and mechanical
properties and are stable to high temperature and chemical environments.
2.4 Focus area: Advanced Processing Technologies
Modelling of sophisticated processing methods can be of valuable importance, as it may shortcut
elaborate trial and error based development. Advanced processing such as two-component
injection moulding and multi-layer extrusion can be used to create structured materials.
Production of components with micro and nanometer structures is another important research
area. Modelling is important to understand and examine different process geometries and
conditions.
Investigation of surface and microstructure formation in injection moulding of plastic
components. (Henrik Pedersen).
This project concerns the investigation of surface formation, on nano and micro scale, of
injection moulded polymer components under the influence of various processing conditions.
The purpose is twofold:
1. To develop commercial optical sensors based on injection moulded diffractive polymer chips
2. To develop techniques for generating optical verification holograms in conventional injection
moulded plastic components.
The techniques used include fabrication of various nano and microstructures in nickel shims,
which are inserted in conventional injection moulding equipment, variations of process
conditions and investigation of surface topography by optical photospectroscopy, atomic force
microscopy and optical microscopy.

Computer aided experimental optimisation of injection moulding. (Erik M. Kjær).
Injection moulding is a very important process for processing of plastics. The outcome of the
processing is a complicated cooperation between product geometry, material and processing
parameters.
The analysis of the processing parameters can lead to optimising of the product and its
production costs.
The aim of the project is to set up criteria’s for optimal processing parameters and how to
determine their values and to design an experimental method for optimising the parameters aided
by results from simulations, measurements and control of the process. Ph.D. student Uffe R. Arlø
is funded by DTU for the project.
2.5 Focus area: Polymer composites
Polymer composites reinforced with biofibers. (David Placket).
The main goal of this project has been to fabricate biofiber-reinforced thermoplastic composites
using a film-stacking technique and to then investigate material characteristics with a view to
optimising key properties. Jute in the form of a mat has been used as a model biofiber in
combination with polypropylene, polycaprolactone (PCL) or biopolymers such as L-polylactide
(PLLA) or polyhydroxybutyrate (PHB). The most significant result of the work during 2000 was
the drafting of a patent application covering a new procedure for biofiber/thermoplastic
compatibility. Scanning electron microscopy and optical microscopy have been used to illustrate
biofiber/polymer interfaces in the composites.
2.6 Externally financed projects
Photo Electrochemical Solar Cells (PEC solceller). (Frederik Krebs).
The main objective of this project is to model and characterise the dynamics of solar energy
conversion in dye sensitised photo electrodes, and to identify the rate limiting elements in PEC
solar cells. The project is co-financed by a STVF talent project.
ARTMUS - artificial muscles. (Peter Sommer Larsen).
The main objective of the project is to conduct an oriented research effort resulting in the
development of a novel class of electrically controlled actuators based on polymer materials. We
aim at an actuator with properties similar to those required by a dextrous robotic gripper: lifting
0.1 kg over 1 cm in 0.1 s. A further goal is to educate researchers with experience in applied
materials science.
With respect to product development, the project is limited to demonstrating that a simple device
- a “demonstrator” - driven by artificial muscles can be constructed. The performance of the
actuators will, however, also be evaluated with respect to other specific applications.
Page 13

Topographical and chemical nanostructuring of polymer surfaces. (Niels B. Larsen, Nikolaj
Gadegaard, Stephan Mosler).
To be able to control the topography and chemistry of polymer surfaces on lateral scales below
100 nanometer. Such polymer surface patterning procedures will be applied to the fabrication of
cell culturing supports that mimic the topography and chemistry of nanostructures in tissue, e.g.
connective tissue.
Injection moulding is targeted as the main tool for producing topographically nanostructured
surfaces. The processes involve generation of master structures of biological origin, mould
generation and injection moulding. The topography of surfaces resulting from each process step
is verified by AFM and microscopy. The final molded polymer objects must expose a cell
compatible surface chemistry, which is investigated by surface chemical analysis by XPS, TOF-
SIMS and contact angle goniometry. Finally, the cell response is monitored by fluorescence or
confocal fluorescence laser scanning microscopy.
Quantification of polymer surface chemistry (linked to the Center contract Center for Surface
Metrology and Functionality, COMF). (Niels B. Larsen, Kion Norrman, Peter Kingshott).
The project will develop procedures to identify and quantify the amount of chemical species
present at polymer surfaces. The objective is to find reproducible methodologies to quantify the
amount of chemical species at polymer surfaces, with particular focus on organic species. The
accuracy and reproducibility of advanced surface chemical instrumentation is found based on
analysis of polymer thin films of defined coverage and thickness. The extent of surface
segregation of non-compatible blocks in selected block copolymers is determined.
Protein adhesion to polymer surfaces (linked to the Center contract Optimisation of Hygienic
Design of Food Processing Equipment, HYDEKO). (Niels Bent Larsen and Peter Szaboe).
The project goal is to understand and control the adsorption of proteins to polymer surfaces. The
project aims at understanding the influence of chemical and topographical surface characteristics
to the adsorption of biomolecules to polymers and to control such adsorption by specific surface
modifications. The surface characteristics of a range of industrial polymers and model surfaces
are described followed by in-situ and ex-situ investigations of the adsorption of proteins.
Subsequently, chemical surface modification of selected polymers is performed to affect a
reduction in the adsorbed protein mass.
