1998 9       31  5               Sep. 1998 JOURNAL OF TIANJIN UNIVER SITY  Vol. 31 No. 5  * 许鑫华  陈贻瑞 方洞浦 燕 妮 ()   具有星形结构的聚 2-甲基丙烯酰氧乙基三甲基氯化铵与 2-甲基吡啶季铵盐和无水三氧 - 1 - 1 化铝形成的熔盐进 复合,得到室温离子电导率高达 10 S·m 的新型固体电解质,它具有优异 的低温导电性能.本文探讨了高分子与熔盐复合体系的导电机理、性能及影响因素 ,并用13 C NM 谱对接枝聚合物进 了表征.  ,,,   631. 23 O A NOVEL SOLID STATE POLYMER ELECTROLYTE OF QUATERNARY AMMON IUM SALT Xu Xinhua Chen Yiru i Fang Dongpu Yan N i ( School of Material Science and Engineering, Tianjin University) Abs rac   A novel solid polymer electrolyte was prepared. As the polymer body, the star-style graft copolymer of 2-methacryloyloxythyltrimethyl ammonium chloride onto tetrahydroxy polyethylene glycol with ceric ammonium sulfate as the initiator has been studied The grafting. 13 products were characterized by  C NM . The ionic conductivity of the star-style copolymer com- 13 plexes containing ionic conduc C made of 2-methylpyridine quaternary ammonium salt and anhy- drous aluminum chloridewas investigated The mechanism of the conduction and thefactors affect-. ing the properties of the complexes were discussed. The room temperature conductivity of the com- - 1 - 1 plex can reach a value of 10 S·m . Keywords  solid state polymer electrolyte, super ionic conductivity, star-style graft copolymer, polymer of quaternary ammonium salt   -( - ) ,
