Hybrid polymer nanomaterials based on N-substituted polyanilines and graphene oxide are synthesized for the first time via the in situ oxidative polymerization of 3,6-dianiline-2,5-dichloro-1,4-benzoquinone and 3,6-phenylenediamine-2,5-dichloro-1,4-benzoquinone in the presence of graphene oxide. The morphology and electrochemical properties of composite electrodes made of graphite foil support covered with polyaniline (or nanocomposites based on its derivatives containing the polyaniline chain with electroactive N-substituents and graphene oxide) coating are studied. It is shown that the electroconductive nanocomposite material characterized by the electrochemical capacitance above 1000 F/g and the stability of capacitive characteristics under prolonged charge/discharge cycles in a proton (1М H2SO4) electrolyte is formed on the graphite foil support.
