Graphene/Fe3O4/Ni nano-composite materials were prepared by one-step hydrothermal method from RGO, FeCl3 center dot 6H(2)O and purity Ni. The structure and electromagnetic microwave absorbing properties were investigated systematically by field emission scanning electron microscope (FESEM), X-ray diffractometer (XRD), X-ray photoelectron spectroscopy (XPS) and vector network analyzer (VNA). The reflectance was simulated based on the electromagnetic parameters to evaluate the absorption properties of the sample. The results show that Fe3O4 and Ni are on the surface of graphene evenly, the composites exhibit excellent microwave absorption properties, reflection loss and broad effective absorption bandwidth are -16.38 dB and 3.60 GHz, as the paraffin wax is 40% and the matching thickness is 2.00-3.50 mm.
