摘要： 本文研究了二甲氧基聚乙二醇(PEGDME)对聚合物电解质膜的影响。结果表明,PEGDME增塑的(环氧乙烷-环氧丙烷-烯丙基缩水甘油醚)三元共聚物-LiClO4络合物具有较低的玻璃化转变温度,室温导电率≥10-4Scm-1,热稳定性及力学性能良好,在100℃下无相分离,室温下在干燥器中放置一年无蠕变。

Abstract: A new kind of polymeric electrolyte film with low glass transition temperature and high room temperature conductivity was prepared by plasticizing the complex of poly(ethy-lene oxide-propylene oxide-allyl glycidyl ether)and LiClO4 with dimethoxy poly(ethyleneglycol)(PEGDME). The effect of plasticizer content on the conductivity of electrolytewas studied. The plasticized electrolyte films showed both a good thermal stability and a good mechanical property. A room temperature conductivity as high as 2?10-4Scm-1 was obtained for film with 60%(vol)plasticizer. The mclecular weight of the plasticizer as a function of conductity was discussed as well.

Key words: polyethylene glycol, polymer electrolyte, conductivity, lithium perchlorate
