초록

기능성 도핑제인 di(2-ethylhexyl) sulfosuccinate sodium salt (NaDEHS)을 사용하여 화학적, 전기화학적 방법에 의한 연신성 폴리피롤을 합성하였다. 화학적, 전기화학적 방법에 의해 제조된 폴리피롤 필름은 구역 연신 방법을 사용하여 1.0 ~ 2.5배 연신시킬 수 있었으며, 연신된 폴리피롤 필름의 전기 전도도를 측정하였다. 연신율이 증가함에 따라 필름의 전기 전도도는 증가함을 볼 수 있었다. 이러한 현상은 연신율에 따른 결정성 증가로 설명할 수 있었다. 온도변화에 따른 전하 이동 경로는 1.0 ~ 2.0배 연신된 폴리피롤의 경우 3차원 variable range hopping 모델, 2.5배 연신된 폴리피롤의 경우 1차원 VRH 모델에 적합함을 볼 수 있었다.

Stretchable polypyrrole films using functionalized doping agent, di(2-ethylhexyl) sulfosuccinate sodium salt (NaDEHS), were synthesized by chemical and electrochemical method. Chemically and electrochemically prepared polypyrrole films were stretch-oriented (L/L₀=1.0 ~ 2.5) by zone drawing method and the electrical conductivities were measured. As the draw ratio was increased, the electrical conductivities were increased. This result was confirmed by the increase in crystallinity through the increase in draw ratio. The temperature dependence of electrical conductivity showed that 3D-variable range hopping model (L/L₀=1.0 ~ 2.0) and ID-VRH model (L/L₀=2.5) gave the best fit to the data for stretched Ppy-DEHS films.
