Abstract

A new approach for the fabrication of organic-organic conducting composite thin films using simultaneous covaporization vapor phase polymerization (SC-VPP) of two monomers that have different polymerization mechanisms (i.e., oxidation-coupling polymerization and radical polymerization) has been reported for the first time. In this study, a PPy-PAN composite thin film consisting of polypyrrole (PPy) and polyacrylonitrile (PAN) were prepared by the SC-VPP process. The preparation of the two types of organic-organic conductive composite thin films was confirmed through FTIR and 1H NMR analysis. The PPy-PAN thin film had a smaller grain size and relatively smoother surface than the PPy thin film. PPy-PAN showed similar electrical conductivity to PPy due to its smooth surface morphology. The contact angle of PPy-PAN was below 30o, which means the surface property was changed to hydrophilic character. The proposed SC-VPP-based hybrid materials allow for control of the surface properties, such as hydrophilicity, of the resulting thin films.


본 연구에서 서로 다른 중합 메커니즘을 가진 두 개의 단량체(즉, 산화 커플링 중합과 라디칼 중합)를 동시에 공-증발 기상 중합(SC-VPP) 수행하여 유기-유기 전도성 복합 박막을 제조하는 새로운 접근법을 보고한다. SC-VPP 공정을 통해 폴리피롤(PPy)과 폴리아크릴로니트릴(PAN)로 구성된 PPy-PAN 복합 박막을 제조하였다. 두 종류의 유기-유기 전도성 복합 박막의 제조는 FTIR 및 1H NMR 분석을 통해 확인되었다. PPy-PAN 박막은 입자 크기가 작고 PPy 박막보다 상대적으로 매끄러운 표면을 가졌다. PPy-PAN은 부드러운 표면 형태로 인해 PPy와 유사한 전기전도성을 보였다. PPy-PAN의 접촉각은 30o 이하로 표면 특성을 친수성으로 조절하였다. 본 고에서 제안된 SCVPP 기반 전도성 하이브리드 박막 소재의 개질 기술로 다양한 디바이스 계면에서의 특성을 조절가능하리라 기대한다.
