Studying Dielectric Properties of Polystyrene-Bentonite Composite and Effective Parameters

Abstract

Samples of composite material have been prepared by using raw material like poly styrene as matrix material,Bentonite Al-Suffra (filler material),Poly vinyl alcohol (binder material) with the state ratios in the research . After preparing Bentonite powder, it had been choose particle size smaller than (100 μm) and after conducting the toasting process to powder with different temperature degrees (100,200,300,400 οC) have been added to dissolved polystyrene material in tolouene with the state ratios and temperature degrees (70-80 οC) have been used also binder material poly vinyl alcohol (PVA) and have been studied dielectric properties for the material (Impedance, Loss factor,A.C.conductivity,Dielecric constant) and study of effect temperature , rate of filler and frequency in value of dielectric constant .
