▎ 摘　　要

The novel high hydrophobic graphene/vinyl-functionalized SiO(2)composites were prepared via self-assembly of graphene sheets on the surface of vinyl-functionalized silica (VF-SiO2) nanoparticles. The resulting graphene/functionalized SiO(2)composites exhibited rapid absorption rate, high absorption capacity and convenient separation in oil-water separation. Furthermore, the composites could be easily recovered and reused at least 12 times without any loss of its activity and showed great potential for large-scale application in water treatment.
