Abstract: The UV-vis absorption properties of polyvinyl alcohol (PVA) membranes containing 0.04 ml silver nanoparticles were investigated by UV-vis spectroscopy. The samples were investigated in initial state and after UV and gamma exposure. Some modification appears in the spectra of samples containing AgNPs after gamma irradiation. This behaviour indicates modifications induced in the local structure of the polymeric membranes. Keywords: Poly (vinyl alcohol), AgNPs, gamma irradiation, UV-vis spectroscopy |
