STUDIES ON THE CONDUCTING POLYMER OF THIOPHENE

Thiophene during chemical peroxidation catalysed by Cu2+ undergoes sim ultaneous polymerization and oxidation. The polymer is characterised b y chemical analysis, solution viscosity, Infra-red and UV-visible spec tre. UV-visible spectra indicate the presence of a band due to pi - pi transition and an exciton band due to interband transition. The poly mer is thermally stable and the temperature dependence of electrical c onuctivity is used to understand the conduction mechanism which is fou nd to 'hopping' charge from state to state.
