Studying the Effect of KCl Addition on the Electrical Properties of Polystyrene

Abstract

In this work, samples of pure polystyrene and polystyrene (PS) doped with (KCl) were prepared using casting method .The effect of addition of different concentrations of potassium chloride on electrical properties of polystyrene have been studied, also the effect of temperature on (PS-KCl) composite , then the variation of activation energy of D.C electrical conductivity with KCl concentrations was studied. The results show that the electrical conductivity was increased with increasing the KCl concentration and temperature and the activation energy was decreased with increasing KCl concentration.

Key words: polymer, PS, potassium chloride, electrical properties, conductivity.
