Preparation and Characterization of Graphene Nanoplatelet/Magnetite Compound Powders

Abstract:

Graphene nanoplatelet（GN）/ Magnetite compound powders with magnetite nano-particles coated on the surface of graphite sheets has been successfully prepared by the wet-chemical co-precipitation. The effects of reaction temperature and mole ratio of Fe2+/Fe3+ on ultimate products were investigated. It has been found that excellent magnetite/GN compound powders were obtained at 30 °C with the Fe2+/Fe3+ mole ratio of 5:1. The composition, structure and the electric and magnetic properties of products were characterized by X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, vibrating-sample magnetometer and four-point probe resistivity measurement.The compound powders have also exhibited the ferromagnetic properties at room temperature.
