摘要: 本文系统地研究了高氯酸锂的二甲基硅氧烷-环氧乙烷共聚物溶液(简写为DMS:EO:LiClO_4)的电导和弛豫随温度和盐浓度的变化规律。浓度为0.394 molL~(-1)时室温电导率达到极大值, 大于10~(-4)S cm~(-1)。
通过比较发现, DMS与PEO形成共聚物并含有易离解的盐将促进离子运动。本文也提到只通过加热使这种溶液固化成膜的方法及膜的电导。

Abstract: The conductivity and relaxation of the solutions of LiClO_4 in dimethyl siloxane-ethylene oxide copolymer (named DMS:EO:LiClO_4 for short) have been investigated systematically. The value of optimum of the conductivity is higher than 10~(-4)Scm~(-1) at room temperature at 0.394 mol L~(-1).
From comparison it was pointed that containing siloxane and the salts easy to be disoeiated in copolymer with PEO is helpful for promoting motion of ions.
The peparation and conductivity of the films obtained from the solution only by heat were also mentioned.
