Polymer/metals nanocomposite films were investigated from aqueous solutions of polyvinyl alcohol (PVA)/acrylic acid (AAc) using UV radiation. The formation of metal nanoparticles (NPs) was characterized by transmission electron microscopy (TEM), Fourier-transform infrared spectrometry (FTIR) and UV-vis spectroscopy. It was found that UV radiation induced the reduction of the metal ions in the polymer matrix into metal nanoparticles. The electrical properties and the anti-microbial efficiency were carried out for the prepared compositions. The maximum AC conductivity was observed in the composites containing Ag NPs. Finally, a green method has been suggested for the development of conductive nano polymer/metal composites that can be used in biomedical applications.
