Abstract

Polycarbonate(PC)/polypyrrole(PPy) conducting composites were prepared by precipitation polymerization. $FeCl_3$, pyrrole and chloroform were used as oxidant, monomer, and solvent, respectively. The electrical conductivity was increased with increasing the amount of PPy, while the mechanical property was decreased. When the PPy content was 25 wt %, the electrical conductivity of the composites was increased up to 0.23 S/cm. The electrical conductivity, the stability of conductivity in air and mechanical properties of the composites of different PPy content were investigated and the morphology of the composite films was observed.
