摘要：

The ionic conductivity of PVC-ENR-LiClO4 (PVC, polyvinyl chloride; ENR, epoxidized natural rubber) as a function of LiClO4 concentration, ENR concentration, temperature, and radiation dose of electron beam crosslinking has been studied. The electrolyte samples were prepared by solution casting technique. Their ionic conductivities were measured using the impedance spectroscopy technique. It was observed that the relationship between the concentration of salt, as well as temperature, and conductivity were linear. The electrolyte conductivity increases with ENR concentration. This relationship was discussed using the number of charge carrier theory. The conductivity-temperature behaviour of the electrolyte is Arrhenian. The conductivity also varies with the radiation dose of the electron beam cross-linking. The highest room temperature conductivity of the electrolyte of 8.5 x 10(-7) S/cm was obtained at 30% by weight of LiClO4. The activation energy, Ea and pre-exponential factor, sigma(o), are 1.4 x 10(-2) eV and 1.5 x 10(-11) S/cm, respectively
