The method of hydrothermal reduction was used to reduce graphite oxide (GO) and a series of experiments were made to investigate the influence of hydrothermal temperature, time and concentration on the reduction and dispersion effects. The atomic force Microscopy (AFM), UV/Vis spectroscopy (UV–vis), Fourier transform infrared (FTIR), X-ray diffraction (XRD), and thermogravimetric analysis (TGA) were used to confirm that the black suspension obtained in the critical conditions had been transformed into reduced graphene oxide (RGO). The as-prepared RGO can be dispersed in water forming suspensions with long-term stability without any organic solvents and other substances, which will facilitate the preparation of RGO-polymer composites and its applications.
► Critical conditions was obtained to produce the reduced graphene oxide. ► Non-carbon impurities was not introduced in the products. ► The conductivity of waterborne polyurethane was improved after mixed with reduced graphene oxide.
