Effect of Polystyrene Film Thickness on Some Optical Parameters

Abstract

Films of polystyrene of different thicknesses have been prepared by casting method. Transmission and absorption spectra have been recorded in order to study the effect of increasing thickness on some optical parameters such as transmittance absorptance, refractive index, extinction coefficient, and absorption coefficient, real and imaginary parts of dielectric constant. This study reveals that all these parameters affect by increasing the thickness.
