摘要: 聚环氧乙烷(PEO)及其盐复合物等是一类高分子固体电解质,但PEO易结晶,不利于电导率的提高,可用非晶的环氧丙烷(PO)与之共聚抑制其结晶.因高分子电解质的特性与组成和热历史有关,故本文利用差示扫描量热法(DSC)研究了升、降温速率对该共聚物及其盐复合物的结晶与熔融的影响.

Abstract: The crystallization and melting behaviour of poly(ethylene oxide-co-propylene ox-ide)and its LiClO4 salt complex were studied.It was found that the plain copolymers arestill crystallizable thotigh the degree of crystallinity has been deeply suppressed owing to thepresence of the non-crystallizable propylene oxide component.However,the LiClO4 adductwas hardly to crystallize especially in fast cooling.A detailed examination on the heating andcooling rate dependence of the Tm,△Hm,Tc,△Hc and cold crystallization phenomenon of thespecimens was made.

Key words: thylene oxide propylene oxide copolymer, polymer solid electrolyte, crystalliza-tion, melting
