▎ 摘　　要

Films of a polystyrene composite with covalently linked graphene oxide (graphene oxide content of about 0.01%) are conductive in metal-polymer-metal structures with a film thickness of up to 6 mu m. Therewith additive-free polystyrene synthesized in similar conditions possesses conductivity only when the film thickness is up to 100 nm. The observed effect of increasing the maximum thickness of the conductive layer in the polymeric composite is due to the change in the electronic structure of polystyrene at the interaction with the graphene oxide.
