Abstract

Synthesis of polymer composites poly (vinyl acetate) (PVAc) and polythiopene (PTh) was done by chemical oxidative method using ferric chloride oxidant in methanol with Iodine as a dopant. The dc conductivity as a function of temperature (313-363 K) was measured by two probe method. The maximum value for dc electrical conductivity was found for 10.4 wt % (σ = 9.78x10-10 S/cm).The decrease in conductivity for more Iodine concentration may be due to reduced segmental motion. The temperature dependence conductivity shows percolative behavior and clear cross over from Vogel-Tamman-Fulcher (VTF) to Arrhenius behavior. Ionic conduction was found to be decreased with increase in concentration of Iodine which shows ionic charge transport.
