PREFACE

Scientific research performed in our Institute in 2008 was aimed

at studying chemical problems of two main fields: materials as

well as environmental science.

The goal of the materials chemistry studies was to gain knowledge

about selected new materials in order to assist in their scientific

cognition, their evolution and to develop their production methods. For this purpose,

the details of chemical composition, structure, macroscopic properties and preparation

methods of some structural and functional materials, as models, were studied. Special

attention was paid to nanosized and nanostructured materials.

In environmental chemistry our results concerning the principles of chemistry as well

as the processes and technologies we developed, help reducing the environmental

impact both during production and utilization of materials as well as in production and

consumption of energy. Research is especially important in this field, because processes

involving man-made materials that take place in a natural environment are based mainly

on chemical reactions. As a consequence, chemical knowledge and technologies play a

mayor role.

Both research fields are interdisciplinary and are integrated from the point of view of

both the studied objects and the applied methods. Synthesis and investigation of various

materials systems are very important elements of both fields. In many cases, the same

systems were studied from the point of view of both materials chemistry and environmental

chemistry. As the subjects of our studies and the methods of investigation overlap, we

were able to offer a multidirectional treatment of materials and environmental issues.

Our yearbook informs you about the events and the achieved results of our Institute in

2008. I hope, this report will meet your interest.

4 RESEARCH ACTIVITIES IN 2008

4.1 Research in materials chemistry

4.1.1 Synthesis and characterisation of nanolayers

Imre Bertóti, Klára Kereszturi*, Miklós Mohai, András Tóth

In the framework of investigations aimed at improving the tribological properties of

engineering polymers, the surface of polyethylene terephthalate (PET) was treated by

plasma immersion ion implantation (PIII or PI 3 ) in nitrogen. According to XPS studies,

the incorporation of nitrogen and decrease of surface O/C ratio took place. The bulk

plasmon loss energy of the C 1s peak increased, implying compaction of the surface

layer. Topographic and nanoindentation studies showed the increase of mean surface

roughness and hardness (H), and decrease of elastic modulus (E). Process conditions were

found, under which a fourfold increase was obtained in the abrasive wear resistance, as

determined by multiple nanoscratch measurements. The improvement in wear resistance

was accompanied by the increase in the H/E ratio.

The surface of polytetrafluoroethylene (PTFE) was modified by saddle field fast atom

beam (FAB) source. According to XPS results, upon FAB-treatment the surface F/C value

decreased strongly. The small-scale wear resistance improved, the mean surface roughness

increased and the water contact-angle decreased upon FAB-treatment.

A new version of the XPS MultiQuant program, developed previously in our laboratory

for the quantitative evaluation of X-ray photoelectron spectra, was released. Geometry

parameters of small polyhedra can now be given, which allows modelling of rough surfaces

and more precise determination of thickness values of layers present on rough surfaces

like those of microcrystalline

or granular materials or striated

specimens. The applicability

of the new model and program

was tested on geometrically

structured silicon and aluminium

samples.

4.1.2 Deposition of simple and composite ceramic coatings

Cecília Bartha*, Zoltán Károly, Anna Mária Keszler*, Szilvia Klébert, Ilona Mohai,

János Szépvölgyi

The aim of our research is to prepare coatings of good mechanical and tribiological

properties on metallic and nonmetallic substrates by atmospheric plasma spraying. The

coatings consist of single or multi component ceramics, or nanocomposite based ceramic

structures. This method results in the improvement of the mechanical and chemical

properties of the coated construction materials (eg. excellent wear and corrosion resistance,

hardness, thermal shock resistance etc.)

instead of melt at high temperatures, were also studied. These ceramics are jointly used

with some oxide ceramics that help to form a molten phase

■■ The coatings are comprehensively analysed by various (chemical and phase composition,

structure, thickness, adhesion etc.) methods available either in our Institute or at our

partners

4.1.3 Archeometry

Zoltán May, Klára Szentmihályi

Our main goal is the archaeometrical study of the provenance and production technology

of old, Hungarian historical (medieval) bricks in a complex way, with the help of modern

analytical methods and instruments (XRF, XRD, ICP-AES, TL, CL, ESR). For this

purpose, basic research must be accomplished including the chemical composition of

the raw materials (trace elements of the clay minerals), firing temperatures, and reaction

kinetics and mechanism during firing. On the other hand, we study the influence of these

parameters on the properties of bricks, as well.

The modern bricks produced in Hungary has been widely studied and well documented in

structural and chemical points of view. In contrast to this, Hungarian historical ceramics

and bricks were processed only according to their main style parameters. Only a few

sporadic results can be found from material sciences point of view. For this reason, we

aimed at collecting basic data about the history of technology and methodology of brick

making, using state-of-the-art techniques on selected samples.

Furthermore we intend to create an accessible and handy database about chemical

properties of these historical materials, which can be used for further archaeometrical

research. Such kind of database does not exist at this moment.

In the future, we will expand our studies to

the provenance and production technology of

Hungarian historical ceramics and jewelries, as

well.

4.1.4 Preparation, formulation and analysis of functional particulate

materials

Tivadar Feczkó, Judit Tóth

In the framework of an international project, called BioPowders, it was investigated how

nanostructured chitosan microspheres can be used for enzyme immobilization, and how

they influence the activity of the biocatalyst. The nanostructured biocatalyst supporter was

proved to be useful for biotechnological purposes.

Important results were achieved in industrial use of particulate solids, applicable for

covering material of electrical elements, and in improvement of their characteristics:

ferrite powders were produced with proper magnetic and morphological characteristics.

The rheological properties of ceramics were meliorated by fluid granulation.

Transport processes of soil contaminants were studied. The particle size distribution of

soil samples, mainly determining their behavior, was investigated by laser diffraction

analyzer. Composites of chitosan carrier material were prepared with protein type drug by

mechanically spouted bed dryer.

4.1.5 Synthesis and examination of permanganates and

polygalacturonates

Judit Fodor*, László Kótai, Zoltán May, Klára Szentmihályi

Tetraammine-zinc(II)dipermanganate was prepared, and its structure was elucidated with

XRD and vibrational-spectroscopic methods. It has been stated that the compound has

a cubic lattice consisting of a 3D H-bound network built from blocks formed by four

permanganate anions and four zinc tetraammine cations.

The structure and the presence of certain microenvironments of essential metal complexes

bounded to polygalacturonic acid were studied.

4.1.6 Nanostructured amphiphilic polymer conetworks and their

applications

Gábor Erdődi, Csaba Fodor*, Márton Haraszti, Béla Iván, Gergely Kali*, Péter Mezey*,

Sándor Szabó

Our research with amphiphilic conetworks and hydrogels aims at in part drug delivery as

well as yeast cell immobilization in polymer hydrogels. Poly(N-vinylimidazole) based

amphiphilic conetworks were synthesized for binding different metal ions from aqueous

solutions due to the complex formation of this polymer with positively charged ions. AFM

measurements confirmed nanophase separated structure of the new conetworks. The metal

ion chelating of these conetworks was also studied.

The swelling behavior of the poly(metacrylic acid)-l-polyisobutylene conetworks were

investigated in aqueous solutions containing Ca 2+ , Cu 2+ and La 3+ ions. We have found

that in contrast to the conventional homopolymer hydrogels, these amphiphilic gels did

not collapse. A new process was also developed for the synthesis of APCNs based on

ethoxyethyl acrylate and ethoxyethyl methacrylate monomers. Thermoanalysis of the

conetworks was carried out. Hydrolysis, thermolysis and swelling behavior were studied

by IR spectroscopy.

Successful synthesis of nanosilver containing nanohybrid amphiphilic conetworks based

on poly(N,N-dimethylacrylamide)-l-polyisobutylene was also investigated. Existence of

silver nanoparticles was proved by TEM and UV-VIS spectrophotometry.

We have made attempts for the synthesis of new amphiphilic conetworks, which possess

„intelligent”, thermo-responsive properties. As hydrophilic component, poly(N,N-diethyl

acrylamide) in conjunction with hydrophobic polydimethylsiloxane and polyisobutylene

were used. Such materials can be applied in a wide range of applications from biomaterials

and biotechnology to sensors.

4.1.7 Synthesis of well-defined polymers with narrow polydispersity and

complex architecture via quasiliving radical polymerization

Béla Iván, Amália Soltész*, Ákos Szabó*, István Szanka*, Márta Szesztay

Quasiliving radical polymerizations have been rapidly progressing in recent years. These

new processes have largely extended the capabilities of polymer chemistry. The potential

benefits of these new polymerization technics are related to the unique and improved

physical and chemical properties of the resulting polymers. Due to these inventions,

a variety of new applications have come into view. In comparison to earlier methods,

quasiliving radical polymerizations have huge advantages from both economic and

environmental points of view.

We developed a new synthetic method to produce hyperbranched polymers. On the basis

of kinetics and mechanism of quasiliving radical polymerization, the use of commercially

available monomers (styrene and (meth)acrylates) for the synthesis of hyperbranched

polymers with different functional groups by one-pot reactions is possible. Our research

group has the know-how to exploit quasiliving radical polymerizations in several fruitful

international cooperations. For example, we have a long-term R&D cooperation with the

DuPont Co.

The synthesis of well-defined block copolymers of isobutylene and poly(ethylene oxide)

based macromonomers via quasiliving carbocationic/radical polymerizations was also

explored. These biocompatible polymers might be of great importance in medicinal

applications.

The polymers have been characterized by a gel permeation chromatography (GPC) system

equipped with multi-angle light scattering (MALS) detector and 1H NMR spectroscopy.

4.1.8 Carbocationic polymerization

Gábor Erdődi, Béla Iván, György Kasza*, Viktória Pálfi, Ákos Szabó*, Márta Szesztay,

Klára Verebélyi*

Our research covers studies on the mechanism of quasiliving carbocationic polymerisation

and the modification, and structure related properties of the resulting novel polymers. We

studied the effect of certain additives on the polymerization of isobutylene which leads to

the formation of double bonds at the polymer chain end quantitatively under carbocationic

circumstances.

Polyisobutylene bearing olefinic chain end was successfully functionalized by “thiol-ene”

reactions. This method permits the development of various functional groups in a simple

addition reaction.

Investigations on environmentally benign, “green polymer” syntheses were also carried

out. We have synthesized polystyrene with different structures at room temperature without

the use of chlorinated solvents, and the minimum required concentrations of additives

were also determined.

Taking advantage of a side reaction, considered previously as an undesirable process, we

managed the production of hyperbranched polystyrene. We have explored and verified that

the branched structure is the result of an intramolecular Friedel-Crafts alkylation reaction

between the carbocatonic chain end and a phenyl group along the polymer chain. The

reaction conditions have been optimized in order to control the structure and properties of

the hyperbranched polymers.

4.1.9 Degradation and stabilization of polyolefins

Enikő Földes, János Kovács*, Ildikó Kriston*, János Móczó, Béla Pukánszky,

Károly Renner*

The effects influencing degradation and stability of polyethylene and polypropylene

produced by different catalysts were studied under processing and application conditions.

The role of catalyst residues and processing conditions in the characteristics of

polyethylene and polypropylene were investigated. Relationships were established among

the characteristics of nascent polymer powder, the composition of additive package and the

chemical reactions taking place during the processing of polyethylene. It was established

that the type of phosphorous antioxidants determines the reactions of polyethylene during

processing in the first place.

The differences in the reaction mechanism of various phosphorous antioxidants were

explored by model experiments. We concluded that the efficiency is influenced by both

the reactivity and the self-thermal stability of phosphorous molecule. The effect of acid

scavengers on the efficiency and consumption of antioxidants was studied in polyethylene

and found to depend strongly on the composition of the complete additive package. The

hydrolytic stability of antioxidants was studied in polyethylene pipes in cooperation with

TVK polymer producer. The results are utilized directly in the development of additive

packages for polyolefins improving the competitiveness of the products.

András Sudár*, József Varga

Structure-property relationships and deformation processes under loading were studied in

natural and synthetic polymers, as well as in their composites. Deformation and breaking

mechanism of PP/sawdust composites containing particles of different sizes were studied.

The conclusion was drawn that the stiffness of the composite increases with increasing

filler content, but the modulus is not influenced significantly by the type and amount

of functionalized polymer used as coupling agent. The other mechanical characteristics

depend strongly on the type and amount of coupling agent (maleic anhydride modified

polypropylene). Coupling agents with higher molecular masses and lower functionality

are favorable for obtaining higher mechanical strength and impact resistance.

Significant progress was achieved in the study of layered silicate/polymer nanocomposites

produced by delamination. The structure was also investigated by rheology. The results

showed that the relaxation time is increased by network structure formed as a result of

exfoliation in layered silicate nanocomposites, which is well reflected in the rheological

properties. Parameters describing

quantitatively the changes in

structure were determined by model

calculations. Groups and segments

in cellulose acetate and some natural

polymers of similar structure were

assigned to the α-, β- and γ-relaxation

transitions measured by DMTA.

4.2 Research in environmental chemistry

4.2.1 Research on feedstock recycling of plastics waste

Marianne Blazsó, János Bozi*, Béla Iván, Zsuzsanna Czégény, Emma Jakab,

Györgyi Szarka*, Márta Szesztay

Utilization of Y-zeolite for promoting pyrolytic recycling of polyamide 6,6 and ABS

(acrylonitrile-butadiene-styrene copolymer) has been studied. It was found that the

thermal decomposition of these polymers leading to environmentally dis-trustful nitrogen

containing com-pounds is not

altered significantly. Nevertheless,

the thermal de-composition product

molecules formed under pyrolysis

of these polymers can be converted

over zeolite. The protonic Y-zeolites

are able to denitrogenate pyrolysis

products, while the contaminating

halogen compounds could be

eliminated from the pyrolysate

We have continued our research on

the degradative transformation of PVC to make environmentally advantageous secondary

products. The effect of zinc stearate, a widely used heat stabilizer was investigated to

make the degradation and the appearence of polyene sequences in the polymer backbone

faster at the same time. This

phenomenon permits a new type

of transformation of PVC wastes

in which the PVC containing

reactive double bonds could be

the starting material of secondary

products.

4.2.2 Studies on the utilization of biomass materials

Erika Mészáros, Emma Jakab, Zoltán Sebestyén*, Gábor Várhegyi

A novel environmental-friendly process has been employed for bleaching wood pulps

using laccase enzime and violuric acid mediator at the University of Beira, Portugal. We

have applied a degradative method for the determination of the residual lignin content of

the pulps using in-situ pyrolysis-gas chromatography/mass spectrometry. It was observed

that the distribution of the lignin monomers changed significantly in the pyrograms of

the pulps and the isolated residual lignins. It was established that the functional groups

of lignin undergo similar chemical reactions during enzymatic biobleaching than during

Kraft pulping.

The thermal decomposition reactions

play crucial role in combustion as well

as in various industrial processes, thus,

we studied the thermal decomposition of

biomasses that are abundantly available

as by-products or are suitable for feasible

production in energy plantations. The range

of the samples studied in 2008 included

straws, corn-stalk, sorghum, rice husk and

Ethiopian mustard. Kinetic models were

established that describes well the thermal

decomposition of these substances at

different temperature programs. Though

the studied samples showed a wide

variation in their composition and mineral

matter content, similarities were found in

the kinetics of their thermal behavior.

4.2.3 Atmospheric chemistry studies

The rate constant for the elementary reaction of OH radicals with acetyl-fluoride, CH 3

C(O)

F, and its photodissociation quantum yield (QY) have been determined. A strong negative

inductive effect caused by the F-substituent was observed for the OH-reaction. The effect

was quantified by deriving group-aditivity value for the FCO group. The photodissociation

QY has been found significantly less than unity indicating an important role of physical

quenching in the mechanism. Acetyl-fluoride is a reaction intermediate formed during the

atmospheric degradation of the Freon-substitute HFC-152a (CH 3

CHF 2

). The laboratory

results imply that the atmospheric lifetime of CH 3

C(O)F is relatively short and so its

global warming potential is not significant.

The quenching rate of singlet excited acetone by O 2

has been determined under atmospheric

conditions. The rate constant of this spin forbidden process is comparatively small and the

observed temperature dependence is in accordance with a negative activation energy.

A simple method has been proposed for the synthesis of 3,3’,5,5’-tetra-(trifluoromethyl)-

benzophenone. This molecule possesses very interesting photochemical and photophysical

properties with promising applications in environmental photochemistry.

4.2.4 Environmental electrochemistry

Platinum is getting progressively accumulated in the environment. Because of it a highly

sensitive method for measuring platinum concentration has been developed. This method

is based on deposition of ultra-low quantity of platinum on gold at potentials more positive

than the equilibrium potential.

Basic electrochemical measurements – mostly cyclic voltammetry and impedance

spectroscopy - have been carried out for characterizing adsorption of certain anions and

to study the structure of the double layer on platinum group metals in simple aqueous

binary electrolyte solutions. As it was demonstrated by impedance measurements, the

exchange kinetics of anions can be characterized between outer and inner positions of the

electrochemical double layer.

We have previously elaborated

a method and device for the fast

measurement of electric currents

in the femtoampere range. This

device has been improved and

now it can be used for sensitive

electrochemical measurements employing

ultramicroelectrodes and

also in electrochemical scanning

probe microscopes.

Miklós Prodán, Zoltán Sándor, Péter Szabó

In the framework of an industrial contract, preliminary experiments have been carried out

by geoelectric method to detect and localize underground oil impurities originating from

damaged pipelines. Parallel to this, technology development has been started to mitigate

harm at the contaminated areas, both by impurity fixation and by in site chemical oxidation

(ISCO) methods. To characterize the pipe-transported fluids as possible contaminants,

domestic crude oils and a large number of their lighter derivatives have been analysed

in detail, using GC/MS, HPLC, and UV/VIS methods. Similarly, proper and reliable

analytical methods were developed to determine the concentration and the composition

of the assumed contaminants, both in

soil and groundwater.

Project entitled “Method and

equipment for the regeneration of

active carbon adsorbents used for

air purification in spray painting

manufactures” has been finished in

2008. As a last phase of our activity,

the reference unit of 600 kg/d

capacity, to be used on the spot of

the workshop, was supplied with a

modern process control and data

acquisition system.

4.2.6 Surface coating technologies with reduced VOC emission

Éva Fekete, Béla Lengyel

Low VOC content coating systems that are built up from different solvent borne and

waterborne paints and contain new, environmentally friendly pigments were investigated,

and their resistance to water moisture and salt spray, as well as their lacquer technical

properties were determined.

Painted steel plates after different exposures

The corrosion of base metal (steel) is observable after the removal of painting

After humidity chamber exposure

After salt spray chamber exposure

100 hours 300 hours 100 hours 300 hours

The corrosion resistance and the lacquer technical

properties of coating systems built up on cast iron

and zinc-phosphated steel component parts were

investigated. On the basis of these investigations

environmental-friendly coating systems that acceptably

withstand heat and sparks have been recommended for

painting the external surface of the brakes of railway

carriages. By using waterborne materials cost reduction

and environment protection were both achieved.

13 EXPERTIES

13.1 Department of Plasma Chemistry

Laboratory of Surface and Nanolayer Chemistry

Contact persons: András Tóth, Miklós Mohai

The principal profile of the laboratory is surface analysis, surface modification and layer

deposition. The main areas of collaboration or service offered are as follows:

►► X-ray photoelectron spectroscopy (XPS or ESCA)

This versatile surface analytical method gives information on:

■■

■■

■■

■■

■■

Elements present in the surface layer (qualitative analysis)

Surface composition (quantitative analysis)

Chemical bonding mode, including oxidation state of the elements (chemical

shift)

Depth profile (by sample tilting or ion etching)

Layer thickness

XPS Escascope

Surface analysis by XPS provides information necessary to solve problems regarding:

surface contamination, adhesion, printability, metallization, wettability, corrosion,

functional groups, surface reactivity, wear resistance, flame-proofing, biocompatibility,

antistatic, and antibacterial properties.

51


►► Nanomechanical and nanotribological studies

Two types of measurements are performed in this area:

■■ Dynamic, depth-sensitive nanoindentation, for determining hardness and elastic

modulus of the surface layer of materials

■■ Dynamic scratch-, wear and topographic tests, for determining resistance

to scratch and abrasive wear, and establishing surface roughness, friction

coefficient, and layer thickness

The layer thickness studied ranges between a few nm and several μm. During the dynamic

test the load applied to the diamond head, and the penetration depth, are followed

simultaneously.

►► Wettability studies

Static contact angle is studied by the sessile drop method and the surface free energy is

calculated by various methods.

►► Surface modification and lab-scale deposition of thin layers

■■ The surfaces of polymers, ceramics, glasses, metals, composites and biomaterials

are modified by plasmas and particle beams like glow discharge, plasma beam,

fast atom beam, plasma immersion ion implantation (PIII). In particular, PIII can

be used to modify uniformly, in a single step the surface of irregularly-shaped

devices (nitriding, carburizing, etc.), with the aim of improving hardness, wear

resistance and other properties (e.g., wettability).

■■ Lab-scale deposition of hard and corrosion resistant (nitride, carbide or carbonbased)

coatings is performed by RF and DC magnetron sputtering or PECVD

under various conditions, to achieve targeted compositions and properties.

Thermal Plasma Laboratory

Research projects of the laboratory aim at the study of the chemical reactions occuring

under thermal plasma conditions. For this purpose we operate a 27 MHz / 4 kW and a

3-5 MHz / 30 kW RF plasma reactor, and transferred and non-transferred arc DC plasma

systems of 40 kW power. For the characterization of the starting materials and the products

the following methods are used: bulk and surface chemical composition (ICP-AES, XRF,

N/O analysis, XPS), phase composition (XRD), microscopic techniques (SEM, TEM),

particle size analysis (LDA), physi- and chemisorption.

Laboratory of Functional Nanoparticles

The main activities of the Laboratory involve crystallization, granulation, coating, drying,

mixing, grinding as well as modeling of these processes. Besides keeping in activities

the conventional methods of particle technology our research work is expanded to the

investigations on the preparation of new, tailored nano- and micro structured pure or

composite materials. The research activities are the followings:

53


►► Studies on colloid chemistry and nanostructure of solid products

Contact persons: Judit Tóth, Tivadar Feczkó

Preparation of pure and composite materials of micron and nanometer sizes using

precipitation (salting-out and chemical), co-precipitation, spherical agglomeration and

emulsion methods.

►► Chemical and process engineering research

Contact person: Judit Tóth

Elaboration of chemical, physical, mechanical and other (e.g. combined) processes to

prepare and to treat micron size composite particles with suitable nanostructure, in order to

establish new production methods, techniques and equipment for these kinds of products.

Among them, product recovery by fluid dryer and granulator, drying of heat sensitive

materials in spouted bed reactors, etc. are studied.

Mechanically spouted bed dryer with inert packing
