Abstract
The electrical/optical properties and surface structures of polypyrrole (PPy) thin films, which were prepared by liquid phase polymerization (LPP) and vapor phase polymerization (VPP) of pyrrole using FTS as an initiatior are compared. The PPy thin film prepared by VPP showed superior surface resistance characteristics as compared with that prepared by LPP. We investigated the relation between surface morphology of PPy film and surface resistance by surface characteristic analysis. The surface of PPy thin film prepared by VPP was smoother than that prepared by LPP. Micro-patterned PPy thin film could be prepared effectively using VPP-combined ink-jet printing and soft lithography.

Iron(Ⅲ) p-toluenesulfonate(FTS)를 개시제로 한 pyrrole의 중합에서 용액 중합법(LPP)과 기상 중합법 (VPP)으로 제조된 PPy 박막의 전기/광학적 특성 및 표면구조를 비교하였다. LPP에 비해서 VPP 방법으로 제조된 PPy 박막은 우수한 전기적 특성을 보여주었다. 표면 특성분석을 이용하여 제조된 PPy 필름의 표면 모폴로지와 표면저항과의 상관관계를 검토하였다. VPP 방법으로 제조된 PPy 박막의 표면이 LPP로 제조된 것보다 평탄하였다. VPP를 응용한 잉크젯 프린팅과 소프트 리소그래피를 사용하여 미세 패턴된 PPy 박막을 효과적으로 제조할 수 있었다.
