Polystyrene/ ZnO Nanocomposite Films with Optimized Optical Properties for UV-shielding Applications

Nanostructured dispersed polymeric materials were used a lot in various fields of application due to their improved structural, mechanical, optical and electrical properties than the base polymeric materials. In present research work, ZnO doped polystyrene (PS) films were synthesized at room temperature via solution-cast technique. The characterizations of these nanocomposite films were done using Ultraviolet Visible spectroscopy (UV-Visible), RAMAN, Photoluminescence and X-Ray Diffraction (XRD) techniques. By characterization, the change in optical and structural properties of PS nanocomposite films at different concentrations can be observed. Different parameters like theoretical & experimental density, direct band gap energy, absorption coefficient, generation of trap centres, change in crystallinity along with various structural parameters are reported in this work. This will help in applications of these materials in UV-shielding and optoelectronic devices.
