Abstract
A conducting composite of poly(amideimide)/polypyrrole was Prepared. A sulfonate group was introduced into the structure of poly(amideimide) (PAI) in order to enhance the coulombic interaction between each phase of composite. The effect of ionic group in sulfonated PAI was monitored by mechanical and thermal properties measurement. The presence of coloumbic interaction was indirectly monitored by the examination of morphology, mechanical properties, dopant of composite materials. In the preparation of a conducting polymer composite, the effect of matrix, oxidants/solvent system, and reaction time on the conductivity was examined. As a result, acetonitrile/methanol (90/10) was the best solvent to polymerize pyrrole, and the conductivity was reached to 7×10-2 S/cm with the incorporation of 2 wt.% of polypyrrole into the matrix.

Poly(amideimide) (PAI)를 매트릭스로 하여 전도성 고분자인 Polypyrrole (PPy)과의 복합재료를 제조하였다. 복합재료 각성분간의 정전기적 인력을 유도하기 위하여 PAI의 구조에 solfonate기를 도입하고 sulfonated poly(amideimide) (SPAI) 아이오노머를 제조하였으며 도입된 이온이 기계적, 열적 성질에 미치는 영향을 검토하였다. 또한 복합재료의 몰폴로지, 기계적 성질, 도판트의 종류 등을 비교 검토하여 PPy와 SPAI의 정전기적 인력의 유무를 간접적으로 확인하였으며, 복합재료 제조시에 매트릭스의 종류, 산화제/용매 시스템, 반응시간 등이 전기전도도에 미치는 영향을 검토하였다. 그 결과, 아세토니트릴/메탄올(90/10) 용매시스템에서 pyrrole의 중합이 가장 잘 일어났으며, 약 2wt.%의 PPy가 SPAI 매트릭스에서 중합되었을 때 7×10-2S/cm의 전기 전도도를 나타내었다.
