Abstract
Graphene oxide (GO) and composites based on it are often used to produce graphene-like materials by thermal or chemical reduction, and the reduction method strongly affects the properties of the materials. In this study, a new method was proposed to prepare a conductive composite based on reduced graphene oxide (rGO) with magnetite nanoparticles (NPs) with an average diameter of 18 nm dispersed on its surface. The method consisted of treating a GO-based composite with Fe3O4 on the its surface in supercritical isopropanol. The composites based on GO and rGO and magnetite NPs were investigated by FTIR spectroscopy, X-ray powder diffraction analysis, and scanning electron microscopy. It is shown that the sample compact film of the rGO-based composite has specific surface resistivity is 22 Ω cm–2 and saturation magnetisation is 32.3 emu/g.
