Abstract
In this research polyvinyl alcohol (PVA) films was prepared by casting method at room temperature, the influence of different weights (0.25 , 0.5 , 0.75 ,1 )g for different molecular weight of PVA( 14000 g/mol and 160000 g/mol) was studied . The absorption and transmission were recorded by using UV-Visible spectrophotometer and used to calculate some of optical properties investigated including: Reflectance spectra, Energy gap, Absorption coefficient, Refractive index, Extinction coefficient and Real part, imaginary part of dielectric constants. From results it can be concluded that optical characterization is increase as increasing of concentration and decreasing of molecular weight.
