Abstract

Optical properties of pure and doped poly(vinyl chloride), PVC contain a triazole ring (P), with different concentration of nano titanium oxide TiO2 were studied. The films prepared by using casting technique. Spectra of transmission, absorption and reflaction were used to study the optical parameters. Different parameters such as the absorption coefficient, refractive index, extinction coefficient and energy gap were studied in the spectral range of 200-800nm. In this study we reveals that the doping of TiO2 is effected on the optical properties of PVC contain triazole ring where the transmission spectrum and energy gap values were decreases with increasing percentage. The energy gap is decreased from 5.79 to 3.24 eV. Absorption coefficient, refractive index and extinction coefficient was increased with the increase of TiO2 concentration.
