Nanomaterials can be incorporated into polymeric coatings to enable significant improvement in targeted properties, i.e., scratch resistance, UV resistance, etc. Commercialprocessing methods have been developed to surface treat nanoparticles to render compatibility between the nanoparticle and polymer matrix. In addition, commercial processes to disperse the surface treated nanoparticles have been developed. These integrated technologies allow transparent coatings containing nanoparticles to be formed in a wide range of resin formulations. This paper will address the preparation and analytical characterization ofnanoparticle dispersions in polymer, as well as their performance attributes. Aluminum oxide (Al2O3) nanoparticles was successfully synthesized by Urea decomposition method. synthesized samples weremixed in polystyrene to form composite. The formed composites characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR), The x-ray diffraction pattern indicated that as-synthesized sample had a crystal size was obtained at 600°C calcination temperature. Fourier transform infrared spectra confirmed the presence of composite formation. Experimental result of the composites exhibitedmany activities of under different investigation under process as of next research going to publish in the next session.
