Abstract

Abstract: A highly stable aqueous dispersion of reduced graphene oxide is obtained through the chemical reduction of graphene oxide by hydrazine hydrate in presence of cetyltrimethyl ammonium bromide (CTAB). Herein we report the preparation of reduced graphene particles which can be stably dispersed in water. The surfactant serves an effective role in graphene layer exfoliation. The dispersion in aqueous media has been observed over a week period. The reduced graphene particles were characterized by X -ray Diffraction (XRD), Fourier Transformed Infra-red (FTIR) spectroscopy. The morphology of prepared particles was studied by High Resolution Transmission Electron Microscopy (HRTEM).
