Abstract: Water soluble graphene oxide nanoplatelets and reduced graphene oxide were prepared from highly oriented pyrolytic graphite (HOPG) and from graphite waste powder. This graphite waste has been used to reuse an industrial waste product and therefore, to reduce production cost of the graphene. A chemical oxidation method was used for the graphene oxide preparation followed by sonication. The reduced graphene oxide was obtained by a graphene oxide nanoplatelets chemical reduction. Characterisation was performed using Fourier transform infrared (FTIR), X-ray diffraction (XRD), Raman spectroscopy and atomic force microscopy (AFM).
