Preparation of (PS-PMMA-ZnCl2) Composites and Study their Electrical and Optical Properties

In this paper, Effect of Zinc chloride on optical and electrical properties of (PS-PMMA) copolymer have been investigated. The samples of composites prepared by using casting technique. The optical properties measured in the wavelength range from 200 nm to 800 nm. The experimental results showed that the absorbance, absorption coefficient, energy band gap, extinction coefficient, refractive index and real and imaginary parts of dielectric constants are increasing with the increase of the Zinc chloride concentration. The electrical properties measured in temperature range from 300C to 800C. The results showed that the D. C electrical conductivity (PS-PMMA) copolymer is increased with the increasing of the weight percentages of Zinc chloride and temperature. The activation energy of composites decreases with increase of Zinc chloride concentration.
