Current and surface topographies of composite based on polystyrene with reduced graphene oxide were investigated using atomic force microscopy. Different substrates such as gold, silicon and graphite were used for this purpose. The strong influence of the substrate’s nature on the current distribution map I(x; y) and the current-voltage characteristics was observed. This effect can be related to different adhesion of composite on the investigated substrates.
Keywords: reduced graphene oxide, polystyrene, composite, resistance, atomic force microscopy.
