Abstract The novel high hydrophobic graphene/vinyl-functionalized SiO2 composites were prepared via self-assembly of graphene sheets on the surface of vinyl-functionalized silica (VF-SiO2) nanoparticles. The resulting graphene/functionalized SiO2 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.

高疏水性石墨烯/功能化SiO2复合材料作为油水分离的有效吸收剂

摘要 通过在乙烯基官能化二氧化硅 (VF-SiO2) 纳米粒子表面自组装石墨烯片，制备了新型高疏水性石墨烯/乙烯基官能化 SiO2 复合材料。所得石墨烯/功能化SiO2复合材料在油水分离中表现出吸收速度快、吸收能力高和分离方便。此外，复合材料可以很容易地回收和重复使用至少 12 次而不会损失其活性，并且在水处理中显示出大规模应用的巨大潜力。
