“…This was a result of a more difficult creation of graphene percolation pathways. The conductivity of the spinel particles was at the level of matrix conductivity (wax) [33,34], forming insulation bridges between the graphene platelets. Schematic creation of bridges is shown in the Fig.…”

A series of nanocomposite graphene/CoFe 2 O 4 and graphene/NiFe 2 O 4 hybrid materials was synthesized via facile, one-pot solvothermal route. The materials were obtained using two pressure methods: synthesis in the autoclave and synthesis in the microwave solvothermal reactor. The use of a microwave reactor enabled to significantly shorten the synthesis time up to 15 min. All the syntheses were carried out in a solution of ethanol. The effect of processing conditions and composite composition on the physicochemical properties and electric conductivity was studied. The specific surface area, density, morphology, phase composition, thermal properties and electric conductivity of the obtained composites were investigated. The results of studies of composites obtained in an autoclave and in a microwave reactor were compared.
