Silver polyanilinenano composite thin films deposited on glass substrates by in-situ aerosol assisted plasma polymerization at atmospheric pressure and room temperature, from aniline monomer in the presence of different concentrations of Ag nanoparticles. The silver nanoparticle with 50nm average particles size was prepared in our laboratory by electrical exploding weir method. Metal polymer nanocomposite thin films were characterized by UV-VIS, XRD, FTIR, AFM and SEM the optical studies show that the energy band gap will be different according to the silver polyaniline concentration. The XRD pattern indicates that the synthesized Ag-polyaniline nanocomposite is amorphous. FTIR reveals the presence of silver nanoparticle embedded into polyaniline.AFM and SEM surface images show that the silver nanoparticle impeded homogenously inside the polyaniline matrices. It can be concluded that it can be preparedAg\ polyanilinenano composite thin films by aerosol assisted dielectric barrier discharge DBD plasma jet polymerization and control the optical energy band gap irregulars by controlling the experiment variables.
