Improvement of optical properties of polystyrene by using (Ni-SED)

Abstract

At this work a membrane of pure and impurified of polystyrene by the addition of the complex(Ni-SED) using the doping (0.025,0.05,0.1,0.2,0.3)% at thickness (65000± 500)nm for all membranes ,Optical constant and properties were investigated through Transmitting and Absorption at range (200-1100)nm. The study showed that the Transmitting had been dropped from (88-77)% at the high percent of doping besides . That the increase of doping ratios led to shift of the Absorption edge from Ultraviolet at wavelength 280nm to beginning of visible region at 400nm.The increase of impurification led to an increase at the values of Optical constants in such a way that the refractive index and imaginary part of dielectric constant at high impurificatoin ratio at 700nm. .
