Abstract
Analysis of the experimentally established transmission variation (taking into account the transparency increasing) of polyvinyl alcohol thin films sensitized with graphene oxide of different concentrations was performed. The mechanical features of these solid-state compositions were studied. Transmission spectra in the visible and near-infrared ranges were registered. The microhardness of the studied materials was measured. The experimental results were confirmed by the quantum chemical modeling. A wide range of possible applications of the studied materials is proposed: display technology, light modulators, laser radiation converters, output windows of optoelectronic devices, biomedicine.

Keywords: polyvinyl alcohol, graphene oxide, nanoparticle sensitization process, thin films, light polarizers, liquid crystals, transmission spectra, microhardness, wetting angle
