Preparation of (PS-PMMA) Copolymer and Study The Effect of Sodium Fluoride on Its Optical Properties

Abstract

Composites materials are used in many applications: solar cells, elements, light emitting diodes (LED), optoelectronic device, industrial applications in aircraft, military and car industry for their low cost, light weight, electrical properties, mechanical and optical properties. In this work, preparation of PS-PMMA copolymer have been investigated.  The sodium fluoride was add to PS-PMMA copolymer with concentrations are (0,1,2,3) wt.%. The samples were prepared casting technique. The optical properties of composites in the wavelength range (200-800) nm. The results showed that the absorption coefficient, extinction coefficient, refractive index and  real and imaginary dielectric constants PS-PMMA copolymer are increasing with increase the sodium fluoride concentration.
