초록

플라즈마 처리가 나일론 6 직물의 표면 특성과 폴리아닐린/나일론 6 복합직물의 전도도에 미치는 영향을 연구하였다. 산소 플라즈마로 처리한 나일론 6 직물의 표면을 XPS 분석을 통해 확인한 결과, C-O, C-OH 등의 관능기가 도입되었으며, 이는 직물과 폴리아닐린의 결합력을 향상시켜 전기 전도도와 폴리아닐린 부착량을 증가시켰다. 또한 사소 플라즈마로 처리된 폴리아닐린/나일론 6 복합직물은 세탁과 마모에서도 우수한 안정성을 나타내었다. 초음파 처리는 매질에 발생된 cavitation과 진동에 의해 직물 내부로 아닐린을 확산시키는데 효과적이었으며, 이는 폴리아닐린/나일론 6 복합직물의 전기 전도도를 크게 향상시켰다. 아닐린의 농도와 중합욕에 침지 횟수가 증가함에 따라 전기 전도도와 복합직물의 형태안정성에 대한 영향을 살펴보았는데, 단량체 농도는 0.5M 까진는 증가함에 따라 전도도가 향상되었으며, 침지 횟수가 증가함에 따라서도 전도도가 향상되었다.

Electrically conductive composites have been prepared by treating fabrics with oxidizing agent aand exposing them to aniline, which deposited a substantial amount of conductive polymer within the interstices of the material. However the coductivity of the composite fabrics was limited by the irregular deposition of the conductive polymer layer. To improe the conductivity of polyaniline/nylon 6 composite fabrics, we modified the surface characteristics of nylon 6 fabrics by various plasma treatment and increased diffusion and adsorption of aniline by ultrasonic treatment. By the oxygen plasma treatment, attachment of functional groups such as C-O and C-OH increased on the surface of nylon 6 fiber, which promoted adhesion to polyaniline resulting in the higher add-on and electrical conductivity. Electrical conductivities of polyaniline/nylon 6 composites fabrics were highly increased by ultrasonic treatment, which assisted the diffusion of aniline into the inside of nylon fabrics by cavitation and vibration. Also, the effects of monomer concentration and the number of deposition cycles on the nylon 6 fabric conductivity were investigated. As a result, the fabric conductivity increased with the monmer concentration and the number of polymerization deposition cycles.
