Abstract: Structural and optical properties of b -Ni(OH) 2 /reduced graphene oxide nanocomposite which was obtained by ultrasound dispersion of hydrothermally synthesized b -Ni(OH) 2 and reduced graphene oxide were investigated. Frequency dependencies of conductivity for initial components and composite materials were studied. Specific surface areas of reduced graphene oxide, b -Ni(OH) 2 and b -Ni(OH) 2 / reduced graphene oxide are 402, 20 and 88 m 2 /g, respectively. It was established that initial ultrafine b -Ni(OH) 2 and b -Ni(OH) 2 /reduced graphene oxide composite have a percolation electrical conductivity. The enlarging of b -Ni(OH) 2 /reduced graphene oxide optical direct band gap energy compared to the initial components due to O/C contents changes was observed.
