The Effect of Ferrous Chloride (FeCl2) on Some Optical Properties of Polystyrene

In the present work, the effect of ferrous chloride FeCl2 addition on some optical properties of polystyrene has been studied. For that purpose, many films have been prepared by adding FeCl2 to the polystyrene with different weight percentages from (FeCl2) with polymer using casting method. The absorbance and transmittance spectrum have been recorded in the wavelength range (190-800) nm. The absorption coefficient, extinction coefficient, refractive index, real and imaginary dielectric constant and energy gap of the indirect allowed transition have been determined.
