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.
