| Abstract: Two types of zinc oxide nanocomposites were synthesized using poly(ethyl hexyl methacrylate (EHM) and poly(butyl methacrylate (BMA) to be applied in manufacturing the molecular switches and the optical memories. The molar ratio of 10/90 was selected for each nanocomposite of ZnO/ PEHM and ZnO/ PBMA to be investigated. The optical characteristics and Raman spectra were conducted at room temperature. Most of the optical studies were sensitively affected by the polymer's chemical nature, composition and the method of interaction. All the prepared nanocomposites were produced, using in-situ chemical oxidative method and deposited using casting solution method. ZnO nanoparticles were combined with PEHMS and PBMA as the polymer matrix physically without the use of surfactants. | ||||
