Synthesis and Dielectric Studies of Polyorthotoluidine - polyvinyl pyrrolidone Conducting Polymer Composites

摘要

The intrinsically conducting polymer, polyorthotoluidine (POT) has been synthesized by chemical polymerization process with the help of water-soluble support polymer polyvinyl pyrrolidone (PVP)). The dielectric measurement of POT-PVP was measured in the temperature range from 308-398 K at frequency 10 kHz. The temperature dependent data has been analyzed in the framework of dielectric permittivity, loss tangent and ac conductivity. Above the temperature 345 K, conductivity shows weak temperature dependence. This is an important feature with respect to technological applications of POT-PVP as an electro-inactive material at high temperature.
