Synthesis of (PS-KBr)‎ composites and studying the effect of KBr addition on the electrical and optical properties of polystyrene

الملخص EN

The aim of this study, preparation of (PS-KBr) composites and study the D.C electrical and optical properties of different concentrations of salt at different temperatures.

The samples of (PS-KBr) composites were prepared by using casting method.

The effect of the concentration of potassium bromide and temperature on the electrical conductivity of polystyrene was studied.

Also, the effect of the concentration of potassium bromide on optical properties has been investigated.

The results show that the electrical conductivity of polystyrene was increased with increasing concentration of potassium bromide and temperature.

Also, the activation energy was decreased with increasing the concentration of potassium bromide.

The optical constants change with increase of potassium bromide concentration.
