Abstract :
The influence of static and dynamic structures on mechanisms of charge transport was investigated by means of isothermal current-voltage dependence for various polymeric materials systems based on poly(vinylchloride) and polyethylene. Poly(vinylchloride) was chemically dehydrochlorinated, thereby creating polyacetylene structures. These samples showed ten-decades-at-best higher conductivity than the precursor polymer in dependence on the concentration of double bonds. Electron spin resonance measurements supported the interpretation of electrical conduction by a hopping transport of electrons. The results obtained for dehydrochlorinated poly(vinylchloride) are compared with model mechanisms of charge transport in polyethylene and partial crystalline polyethylenes as borderline cases
