Abstract
The ionic conductivity and thermal properties of poly(ethylene oxide)/poly (epichlorohydrin) blends containing lithium perchlorate were studied. The amount of salt required for complete disruption of the PEO crystalline phase in PEG/PECH (80:20) blend was much smaller than that in the pure PEG. The ionic conductivities of the PEG-lithium salt mixtures were enhanced by adding PECH, but this was not effective at the higher content of PECH.

리튬염을 함유하는 폴리에틸렌옥시드/폴리에피클로로히드린 블렌드의 이온전도도 및 열적 성질을 조사하였다. 20wt%의 PECH를 함유하는 PEO/PECH 블렌드는 PEO 단독계에 비해 소량의 리튬염을 첨가하더라도 PEO의 결정성이 파괴됨을 확인하였으며, PECH가 첨가됨으로서 이온전도도는 증가하지만 어느 값 이상에서는 더 이상 증가하지 앉았다.
