It was essential to investigate the features of overlapping nanocomposites because of the significance they have in the fields of science, industry, electricity, and medicine. As a result, it garnered a lot of attention and led a lot of scientists and researchers in the direction of studying the features of nanocomposite. Investigations have been conducted into the fabrication of (polystyrene (PS)-zinc oxide (ZnO)) nanocomposites and the examination of the optical characteristics of these nanocomposites for use in optoelectronic applications. Various concentrations for PS polymer & ZnO NPs were used in the fabrication of the nanocomposites using the solution casting process. The results of the experiments performed on (PS-ZnO) nanocomposites appear that each of the absorbance (A), absorption coefficient (α), extinction coefficient (K), refractive index (n), real and imaginary dielectric constants (ε_r  & ε_i ), and optical conductivity (σ_opt ) of polystyrene increase by increasing ZnO NPs concentrations. On other hand, the transmittance (T) and energy gap (E_g )  decrease by increasing ZnO NPs concentrations. Nanocomposites made of zinc oxide have a high absorption in the ultraviolet spectrum.
