The paper presents the experimental results of the composite-materials’ synthesis on the base of nickel hydroxide ?-Ni(OH)2 and reduced graphene oxide using ultrasound dispersion of hydrothermally obtained ?-Ni(OH)2 and previously chemically reduced graphene oxide. The synthesized material is investigated by XRD, SEM, and impedance spectroscopy. The increasing of composite dispersion degree at increasing of carbon-component content is observed. The electrical conductivity of pure ?-Ni(OH)2 and rGO, and ?-Ni(OH)2/rGO composite materials at different ratios of components is analysed at different frequencies in the temperature range of 25–200?C. The decrease in the activation energy of an electric conductivity for the ?-Ni(OH)2/rGO nanocomposite at the component ratio of 1:2, in comparison with pure rGO, is observed.
Key words: nickel hydroxide, reduced graphene oxide, ultrasound dispersion, hydrothermal synthesis, electrical conductivity, electrochemical properties.
