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 ${\pi}-{\pi}$ self-assembled of imidazolium aromatic ring of ionic liquid on polyaniline framework.

전도성 고분자로 널리 알려진 폴리아닐린과 액체전해질의 핵심 재료인 이온성 액체와의 복합체를 형성시키고 이들의 물리적, 전기화학적인 특성을 조사되었다. 이미다졸늄 이온성 액체 (1-methyl-3-propylimidazolium iodide, PMI-I)에 비전도성 폴리아닐린 (Emeraldine Base)을 30 wt%이상 첨가하였을 때 준고형화 현상이 나타났고, 이온성 액체의 이미다졸늄 양이온의 방향족 고리와 폴리아닐린의 벤족기와의 ${\pi}-{\pi}$ 자기상호조립에 의한 약한 도핑작용을 통해 섬유상 구조를 나타내었으며, 전도도의 변화율은 80%이상 유지하였다.
