The composites of polyaniline with reduced graphene oxide (PAni-RGO) are obtained. The structure and physicochemical properties of the composites are studied by means of the methods of elemental analysis, IR and Raman spectroscopy, and electron microscopy. The composites are also tested as electrodes for supercapacitors. As shown, the RGO has high stability during prolonged charge—discharge cycling, but low specific capacitance (≅ 22 F/g), and vice versa, the PAni has a high specific capacitance (800 F/g), but low stability in the charge—discharge cycling. Capacitance and stability of the PAniRGO composites take intermediate values as compared with their constituents. As revealed, the composition of 70 wt.% PAni and 30 wt.% RGO is the most stable in cycling. The specific capacitance for this composition is found to be 300 F/g.
