A Study on the Preparation of Polycarbonate/Polypyrrole Conducting Composite and Their Electrical Properties

초록

침전중합에 의하여 polycarbonate(PC)/polypyrrole(PPy) 전도성 복합체를 제조하였다. 이때 산화제로서 FeCl₃를 단량체로서 pyrrole를 용매로서 chloroform을 사용하였다. PPy의 함량이 증가함에 따라 전기전도도는 증가하였으며 기계적 물성은 감소하였다. PPy의 함량이 25 wt%일 때 전기전도도는 0.23 S/cm까지 향상되었다. 전도성 복합체의 대기중의 산화안정성, 전기전도도의 온도의존성, 몰포로지, 그리고 기계적 물성 등을 측정·분석하였다.

Polycarbonate(PC)/polypyrrole(PPy) conducting composites were prepared by precipitation polymerization. FeCl₃, 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.
