摘要

采用溶液浇铸法将含有不饱和双键的1-烯丙基-3-乙烯基咪唑氯盐(AVImCl)离子液体与聚偏氟乙烯(PVDF)共混成膜，采用γ-射线辐照法对制备的AVImCl/PVDF电解质膜进行改性研究。采用SEM、TG、DSC以及电导率和拉伸测试，对AVImCl/PVDF电解质膜的性能进行了表征。结果表明，离子液体AVImCl经辐照后发生聚合或在PVDF链上发生接枝反应，从而使得辐照后的AVImCl/PVDF电解质膜的热稳定性得到提高，当吸收剂量达60 kGy时，制备的电解质膜具有适宜的电导率和优异的力学性能，拉伸强度和断裂伸长率分别高达23.9 MPa和622%。

Abstract

Radiation modification of the AVImCl/PVDF electrolyte films prepared via casting the mixture of ionic liquid containing unsaturated double bond 1-allyl-3-vinyl imidazole chloride (AVImCl) and poly(vinylidene fluoride) (PVDF) was investigated. The properties of AVImCl/PVDF electrolyte films were characterized by SEM, TG, DSC as well as ionic conductivity and mechanical test. The results showed that AVImCl was polymerized or grafted on PVDF chains under irradiation, contributing to the improvement of thermal stability for modified AVImCl/PVDF electrolyte films. When the dose was 60 kGy, AVImCl/PVDF electrolyte films exhibited appropriate ionic conductivity and excellent mechanical performance accompanied by tensile strength of 23.9 MPa and elongation at break of 622%.Cited
