초록
전도성 고분자로 널리 알려진 폴리아닐린과 액체전해질의 핵심 재료인 이온성 액체와의 복합체를형성시키고 이들의 물리적, 전기화학적인 특성을 조사되었다. 이미다졸늄 이온성 액체 (1-methyl-3-propylimidazolium iodide, PMI-I)에 비전도성 폴리아닐린 (Emeraldine Base)을 30 wt%이상첨가하였을 때 준고형화 현상이 나타났고, 이온성 액체의 이미다졸늄 양이온의 방향족 고리와 폴리아닐린의 벤족기와의 π−π 자기상호조립에 의한 약한 도핑작용을 통해 섬유상 구조를 나타내었으며, 전도도의 변화율은 80%이상 유지하였다.
Abstract
Polyaniline-ionic liquid composite was prepared and investigated its physical and electrochemical properties. The quasi-solidification was presented in imidazolium-based ionic liquid (1-methly-3-propylimidazolium iodide, PMI-I) containing above 30 wt% of polyaniline (emeraldine base), which exhibited around 80% decrease of conductivity compared to pristine ionic liquid, resulting in fibril structure trough π−π self-assembled of imidazolium aromatic ring of ionic liquid on polyaniline framework.
