vpliv interakcij med komplementarnimi<br />

funkcionalnimi skupinami na heterogenost<br />

segmentnega gibanja in na fazne prehode.<br />

- Delo na ionsko prevodnih polimernih<br />

membranah smo nadaljevali s pripravo sklopa<br />

membrane in elektrod (angl. Membrane electrode<br />

assembly, MEA), s katerim smo<br />

preizkusili delovanje lastnih membran v testni<br />

postaji in dolo~ili njihove elektrokemijske<br />

lastnosti.<br />

- Po poliolnem postopku smo sintetizirali<br />

(nano)delce bakrovega (I) oksida, kovinskega<br />

bakra in srebra, cinkovega oksida in nano`i~ke<br />

Cu O v razli~nih diolih. Delci velikosti med 100<br />

2<br />

nm in 10 mm so bili ve~inoma aglomerirani,<br />

na povr{ini pa je bilo adsorbirano topilo, ki<br />

hkrati {~iti delce pred oksidacijo in omogo~a<br />

bolj{o disperzibilnost delcev v organskih<br />

medijih.<br />

- Nanokompozite iz modificiranega montmorilonita<br />

(MMT) in PMMA smo pripravili v<br />

- The molecular dynamics of semi-interpenetrating<br />

polymer networks and polymer mixtures<br />

based on functionalised polyurethanes<br />

and methacrylic copolymers was investigated<br />

by electron spin resonance – spin label<br />

method. The influence of polymer interactions<br />

imposed by complementary functional<br />

groups on motional heterogeneity and phase<br />

transitions was confirmed.<br />

- The research on ion-conducting polymer<br />

membranes was focused on the preparation<br />

of membrane-electrode assemblies (MEA)<br />

which were used to test the electrochemical<br />

characteristics of our own membranes in a<br />

fuel cell test station.<br />

- (Nano)particles of copper (I) oxide, metallic<br />

copper, silver, zinc oxide and nanowires of<br />

copper (I) oxide were synthesized by the<br />

polyol procedure in different diols. Particles<br />

with sizes between 100 nm and 10 mm were<br />

mostly agglomerated. Solvent (diol) was<br />
