本文介绍了一种新的交联聚醚的研究情况。即用丙三醇引发的聚氧乙烯作为预聚物与甲苯二异氰酸酯进行交联,并在交联的同时络合 LiCF_3SO_3盐,形成交联聚合物电解质。研究内容包括:预聚物的合成及表征,交联及成膜工艺研究,聚合物电解质膜的性能研究等。研究表明,这种交联聚醚电解质相对于线型改性聚醚电解质,具有较高的玻璃化温度和很好的力学性能,但导电性能尚有待提高。 This article describes a new cross-linked polyether research. That is, poly (ethylene oxide) initiated with glycerol as a prepolymer is cross-linked with tolylene diisocyanate and the LiCF 3 SO 3 salt is complexed while being cross-linked to form a cross-linked polymer electrolyte. The research contents include the synthesis and characterization of prepolymer, the research of cross-linking and film-forming process and the research of the properties of polymer electrolyte membrane. The results show that the cross-linked polyether electrolyte has higher glass transition temperature and better mechanical properties than linear modified polyether electrolyte, but the conductivity needs to be improved.
