Abstract

An electrically conducting composite material polyacrylonitrile/Polypyrrole (PAN/Ppy) was prepared by sol-gel method. The temperature dependence of the DC electrical conductivity was measured on compressed pellets by using a 4-in-line-probe dc electrical conductivity-measuring instrument. The conductivity values lies in the semiconductor region, i.e., 10-2–10-4 S cm-1 and follow the Arrhenius equation. The thermal stability of the composite material (HCl treated) in terms of dc electrical conductivity retention was studied under isothermal conditions (at 50, 70, 90, 110, 130 and 150 °C) at 15 min intervals. The stability of the material (HCl treated) in terms of electrical conductivity retention was also monitored for five cycles for increasing temperatures at 1 h intervals. The composite material was found thermally and environmentally stable in terms of DC electrical conductivity retention.
