The Effect of Nano TiO2 on the Optical Propertiesof PVCContains TriazoleMoieties

Abstract

Abstract Optical properties of pure and dopedpoly(vinyl chloride) PVCcontaina triazole ring (P),with different concentration of nanotitanium oxide (TiO2)were studied. The films prepared by using casting technique.Spectrums of transmission and absorption was used to study all optical Parameters.Different parameters such as absorption coefficient, refractive index, extinction coefficient and energy gap were studied in the spectral range (200-800)nm. This study reveals that the optical properties of (PVC)containtriazole ring affect by the doping of (TiO2) where The transmission and energy gap value decreases with increasing percentage where the energy gapdecreases from (5.79 to 3.24 )EV.Absorption coefficient,refractive index and extinction coefficient were increased with the increase of (TiO2)concentration.
