Abstract
Highly conducting Nylon 6-Polypyrrole composites can be chemically obtained by exposing Nylon 6 films containing FeC13 to vapour of pyrrole. The surface and bulk conductivities of these composites were in the range of 10-12-10-3S/ cm depending on the concentration of FeCl3 and the polymerization time. From the current-voltage characteristics and temperature dependence of conductivities, we can conclude that the conduction mechanism of Nylon 6-Polypyrrole composites mainly depends on electronic conduction. These composite films were analysed by FT-IR spectroscopy and wide angle X-ray scattering(WAXS). From the WAXS study, there are no appreciable changes of the crystal structure of Nylon 6 composite films, but the formation of α-type crystal of Nylon 6 is suppressed during the polymerization of pyrrole. The dynamic and static mechanical properties were studied with Rheovibron and Instron, respectively. These composite films exhibited good mechanical properties.

FeCl3를 함유하는 Nylon 6 film을 pyrrole monomer의 증기에 노출시켜 높은 전기전도성을 갖는 Nylon 6-Polypyrrole composite를 화학적으로 제조하였다. 이 복합재료의 표면과 체적전도도는 FeCl3의 농도와 중합시간에 따라 10-12-10-3S/ cm의 범위를 나타내었다. 전류-전압특성과 전기전도도의 온도의존 성실험으로 부터 Nylon 6-Polypyrrole composites의 전도 mechanism은 주로 electronic conduction mechanism을 나타내었다. 이 composite film에 대하여 FT-IR spectrum분석과 광각 X-ray 산란 (wide angle X-ray scattering) 실험을 행하였으며, 광각 X-ray산란 실험으로 부터 이 복합재료의 결정구조는 큰 변화는 없었으나, pyrrole이 중합됨에 따라 Nylon 6의 α-type 결성의 형성이 억제되었다. 동력학적 성질 및 기계적 성질을 Rheovibron과 Instron으로 조사하였으며, 그 결과 이복합재료의 물성은 상당히 우수 하였다.
