Abstract

The Optical transmission and UV‐VIS absorption spectra have been recorded for different proportion of PVA and PAM. Transmittance, absorbance, and reflectance of pure and blends polymer are investigated. Optical properties such as the absorption coefficient, optical (Direct/Indirect) energy gap, absorption edge, Refractive index, Constant B are calculated. The effects of different blending percentage on these parameters have been discussed and behaviors of all parameters are investigated.
