Frequency and Temperature Effects on Dielectric Properties of PEDOT-VC Copolymer

The copolymer based on Poly(3, 4-Ethylene dioxythiophen) and Poly(n-Vinylcarbazole) was characterized by FTIR and Raman spectroscopy. The temperature and frequency evolutions of dielectric parameters are also plotted and studied. The dependence of ε” on the temperature shows relaxation process for studied copolymer especially with frequencies about 1kHz for the temperatures: 90°C < T < 118°C. The values of ε’∞, ε’’MAX, relaxation time and DC conductivity corresponding to the copolymer are also determined with the aim to provide dielectric analysis involving vital information about this new polymeric compound
