Ahmed Ali, Ali Razzaq Abdulridha and Talib M. Abbas

Abstract: This study discovers the study effect of Aniline blue dye (ABD) addition on optical properties of polyvinyl alcohol (PVA) and Polyethylene glycol (PEG) blend. The composites samples were prepared by adding (ABD) percentages of 0, 0.013, 0.015, 0.017 and 0.020 wt. (%) to the (PVA-PEG) blend. The films were prepared by casting method with different thicknesses. The absorption noted in range of wavelength 200-800 nm. While the optical constants such as extinction coefficient, absorption coefficient, energy gap of the forbidden transition, indirect allowed, imaginary and real dielectric constants determined. The optical constants improved with improving of (ABD) concentration. The energy gap reduced with reduction the weight percentages of (ABD).
