▎ 摘　　要

The peculiarities of electrochemical polymerization of diphenylamine-2-carboxylic acid (DPAC) in alkaline electrolyte on anodized graphite foil (AGF) are studied with using of electrosynthesis (ES) modifiers (EM), namely, nanosheets of reduced graphene oxide (NSGO) and manganese dioxide. The physicochemical properties of the thus obtained electroactive polymer coatings (PDPAC) as well as their electrochemical characteristics in 1 \M H2SO4 solution in the potential interval from -1 to +1.5 V are studied. The results of electrochemical, electron-microscopic, and X-ray diffraction investigations make it possible presuppose the presence of specific features in the electropolymerization of diphenylamine-2-carboxylic acid on AGF. The calculated values of the electrochemical capacitance and the stability of polymer coatings during their multicycle and charge-discharge tests have shown that the characteristics of these materials are suitable for developing the electrode materials for supercapacitors on their basis.
