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.

Polystyrene films prepared by radical polymerization can conduct electric current in metal-polymer-metal structures with film thicknesses of up to 20 nanometers. Films of polystyrene and graphene oxide composite with thickness up to 3 micrometers, synthesized in similar conditions have the same electric properties. This effect is explained by presence of highly conductive graphene oxide inclusions in the dielectric polystyrene matrix.

Abstract. It is shown that a supercurrent in disordered polymers placed between superconductor electrodes may be explained by resonant tunneling of Coopers pairs along polymer channels formed due to electrification effect. Polymer film thickness where supercurrent one may to observe depends on superconducting coherence length in superconductor. The more coherence length in superconductor electrode the more is a polymer film thickness where superconductor exists. Shapiro steps induced by microwave (f = 9.3 GHz) radiation correspond to a single Josephson junction.

The dependence of polymer conductivity on the work function of metallic electrodes

Abstract: It is shown that the occurrence of metallic conductivity in polymers is due to their electrification. In particular, the current density depends on the electron work function of metallic electrodes which are in contact with the polymer.
