摘要: 聚环氧乙烷(PEO)可以溶解多种碱金属盐并形成络合物,这种络合物具有离子导电性,人们对该特性进行了大量的研究.由于在室温下,PEO通常呈半晶状,而晶区使得离子传输困难,因此电导率不是很高,不能满足实用需要.

Abstract: The comblike polymer based on methyl vinyl ether/maleic anhydride copolymerwith oligo-oxyethylene chains(BM350)dissolved NaClO4,forming a homogeneous amor-phous polymer electrolyte. The Tg of the polymer were found to be increased with salt addi-tion. The BM350/NaClO4 complex at a [Na]/[EO] ratio of 0. 25 exhibited ionic conductivityof 1.03×10 ̄(-4)S/cm at 25℃,The conductivity of the polymer electrolytes obeys the VTF e-quation and has been discussed in terms of the changes in confugurations.

Key words: comblike polymer, NaClO4complex, solid electrolyte, ionic conductivity
