초록

최근에 이온성 액체의 합리적인 물성으로 인해 많은 관심을 받고 있다. 자유 라디칼 중합공정과 친핵성 치환 반응을 이용하여 내구성 있는 3-클로로프로필-트리에톡시실란으로 부분 4차화된 폴리비닐에틸이마다졸륨(C-QPVEm)을 제조하였으며, 이를 열처리를 통하여 가교하였다. 고분자의 물성을 향상시키기 위해 가교 가능한 프로필 에톡시실란을 도입하였다. 합성된 QPVEm을 수소 핵자기 공명 분석과 적외선 분광분석을 이용하여 화학적 구조를 확인하였으며, 순환 전류 전압법을 이용하여 열처리로 가교된 C-QPVEm의 전기화학적 안정성이 향상됨을 확인하였다.

Ionic liquids (ILs) have attracted a lot of interest because of their favorable properties. Durable cross-linked partially quaternized poly(1-vinyl-3-ethylimidazoluim) with 3-chloropropyl-triethoxysilane (C-QPVEm) was fabricated via free radical polymerization and nucleophilic substitution reaction followed by thermal treatment. A cross-linkable propyl- triethoxysilane group was covalently incorporated into the polymer matrix to enhance the properties of the PVEm. The chemical structures of the synthesized pristine and cross-linked QPVEm were confirmed by 1H NMR and FTIR spectra. The electrochemical stability of the C-QPVEm was determined by the CV technique, and found to be significantly improved due to the cross-linked networks in the polymer matrix.
