Abstract
A new electrolyte, tetrabutylammonium dodecylsulfate(TBADS), which is a surfactant with a long aliphatic chain and is soluble in an organic solvent, is synthesized. A polypyrrole film on platinum electrode is formed electrochemically in acetonitrile using TBADS as an electrolyte and shows electrical conductivity of 110S/cm. The electrically conducting polymer reveals a good electrochemical reversibility in cyclic voltammetry and the peak difference in a redox cycle is mere 100mV. The polymer shows tensile strength of 6.08kg/mm2 and elongation of 11.2%, which values exceed those of the polymer formed with an inorganic ion as tile dopant. The polypyrrole film formed in the organic system has better electrical and electrochemical properties than a film formed in an aqueous system with the same dopant.

긴 지방족기가 있는 계면활성제로서 유기용매에 용해되는 새로운 전해질인 테트라부틸암모니움 도데실설페이트(TBADS)를 합성하였으며, 이를 전해질로 사용하여 아세토니트릴(AN) 용매에서 전기중합한 폴리피롤 필름은 전기전도도가 110S/cm이며, 전기화학적 가역성도 우수하여 순환전류 전위곡선에서 산화와 환원피크의 차가 110mv밖에 되지 않았다. 인장강도간 6.08kg/mm2이고 신률이 11.2%가 되어 무기음이온을 도판트로 사용하였을 때보다 훨씬 우수한 기계적 강도를 나타내었다. 또한 수용액하에서 도데실설페이트를 도판트로 했을 때의 폴리피롤 필름보다 우수한 전기특성 필름을 얻었다.
