The Doping Effect on Conductivity and Glass Transition Temperature of Solid Polymeric Electrolyte Based on Polyvinylchloride (pvc)

Solid electrolyte materials have been widely used in electrochemical devices such as batteries, solar cells and displays. This is because of its advantages over the liquidmaterial.This paper is concerned with the preparation of solid polymeric electrolyte based on polyvinylchloride (PVC) and its conductivity .The effect of percentage by weight of dopant material (LiClO₄) on conductivity and glass transition temperature of the electrolyte was studied by using differential scanning calorimeter (DSC) and impedance spectroscopy technique. The electrolyte doped with 4.8%wt LiClO₄ exhibits the highest conductivitiy of 7 × 10^-6Scm^-1 at room temperature but has the lowest glass transition temperature of 36.37°C. The other results are presented in this paper.
