摘要：

Poly(ethylene oxide) modified poly(dimethylsiloxane) has been complexed with LiClO4 or LiCF3SO3. The configuration of these polymers enhances their flexibility. The ionic conductivity has been measured using complex impedance spectroscopy for different Li+ ion concentrations. The temperature dependence of the conductivity has been measured for some of the samples. The ionic conductivity increases more rapidly with the addition of LiClO4 than with LiCF3SO3 but the maximum conductivity is higher for complexes with LiCF3SO3. At room temperature the highest ionic conductivity values were of the order of 9 x 10(-5) OMEGA--1 cm-1 for LiCF3SO3 compounds with the polymer. Effects of viscosity and ethylene oxide chain length are discussed.
