Abstract

In this work, the optical properties of (PS-TiO2-Al2O3) nanocomposites films prepared by casting method have studied. To use in different optical fields. The TiO2 and Al2O3 nano particles added with different weight percentages are (1,2, 3 and 4) wt% were injected air bubbles to generate Nano bubbles in the (PS-TiO2-Al2O3) nanocomposites. The results revealed that absorbance, absorption coefficient, extinction coefficient, and refractive index of the optical characteristics of nanocomposites for wavelength range (280-800) nm. Increase with increase TiO2 and Al2O3concentrations, while the Transmittance decreased with increase TiO2 and Al2O3 concentrations. Optical energy values gap from (3.62 -1.50) eV, where the optical energy gap of produced films reduced as the number of TiO2 and Al2O3 nanoparticles increased.
