聚合物单阳离子导体的制备——羧酸型梳状单离子导体
摘要:
本文报道一种制备聚合物单阳离子导体的新方法。马来酸酐-醋酸乙烯酯及马来酸酐-苯乙烯共聚物以聚乙二醇单甲醚醇解,使酸酐环打开而得到带有聚乙二醇侧链的羧酸型梳状聚合物,其锂盐在加入适当增塑剂成膜后,可作为聚合物单阳离子导体,其结构以非晶态为主,具有较低的玻璃化转变温度及较好的热稳定性,增塑后的室温电导率最高可达10-6S/cm。此外还研究了聚合物结构、阳离子半径、增塑剂、温度及外加频率等因素对电导率的影响。

PREPARATION OF SINGLE-ION POLYMER CONDUCTOR——COMBLIKE POLYMERS WITH CARBOXYLATE GROUPS
Abstract:
The single-ion conducting polymer electrolytes with carboxylate groups immobilized on the backbones have been synthesized by alcoholysis of maleic anhydride-styrene or maleic anhydride-vinyl acetate copolymers with PEO monomethyl ether. The plasticized comblike polymeric lithium salt film showed conductivity up to 10-6 S/cm at room temperature. The effects of polymer structure, cation radius, plasticizer, temperature and frequency on the conductivity were investigated.
