The Effect of Nano TiO2 on the Optical Properties of (PVC) Contains Triazole Moieties/تأثيراوكسيد التيتانيوم الثنائي النانوي على الخصائص البصرية لأغشية بولي فينايل كلورايد المحتوية على حلقة الترايزول

Abstract

Optical properties of pure and doped (poly vinyl chloride) PVC contain a 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) contain triazole ring affect by the doping of (TiO2) where The transmission and energy gap value decreases with increasing percentage where the energy gap decreases from (5.79 to 3.24) EV. Absorption coefficient, refractive index and extinction coefficient were increased with the increase of (TiO2) concentration.
