Superhydrophobic reduced graphene oxide-wrapped melamine sponge(RGO-MS) was prepared via a facile surface modification method with graphene oxide (GO) modification amphipathic melamine sponge (MS). X-ray diffraction (XRD), Raman spectra, Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) were used to investigate the structure, morphology and component of RGO-MS. The mechanical property, hydrophobicity, oil adsorption capacity, reusability and oil/water separation efficiency of RGO-MS were also explored. The results revealed that reduced graphene oxide (RGO) coating was closely linked to MS skeleton. In addition, RGO-MS possesses outstanding adsorption capacity for floating oil and heavy oil underwater, and could maintain ultra-high adsorption capacity even after 50 adsorption-squeezing cycles which is as high as 90 % of its initial adsorption capacity. Moreover, RGO-MS exhibits extremely high separation efficiency up to 4. 5x10(6) L/ (m(3) . h) under non-turbulent and 3x 10(6) U( m(3) . h) under turbulent condition water/oil system. Therefore, RGO-MS has a huge application prospect in dealing with the large-scale removal of oil and organic spillage cleanup.
