摘　　要：氧化石墨烯(graphene oxide,GO)作为石墨烯的衍生物,结构上逐层堆叠,在片层之间能形成一定间距的纳米通道,可根据透过粒子的尺寸进行筛分,从而实现物质的选择性分离。近年来,氧化石墨烯逐渐成为污水处理的新一代膜材料,但氧化石墨烯膜在使用过程中不可避免地存在膜污染问题。本文综述了GO膜的主要制备方法,介绍了GO膜的改性方法,分析了氧化石墨烯膜抗污染表面构建策略及抗污染机制,总结和展望了氧化石墨烯膜的发展方向以及面临的挑战。Graphene oxide(GO),as a graphene derivative,is structurally stacked layer by layer to form nano-channels with a particular spacing between the layers,which can be employed in the selective separation of substances by sieving according to the transmitting particle size.In recent years,graphene oxide is gradually becoming a new kind of membrane materials for wastewater treatment.However,there is an inevitable problem of membrane contamination during the application of GO membranes.In this paper,the main preparation methods of GO membranes were introduced,followed by the introduction of the modification methods of GO membranes.Subsequently,the surface construction strategy for anti-fouling of GO membranes and the anti-fouling mechanism were analyzed.Finally,the development and the challenges of GO membranes were summarized and prospected,respectively.
