摘　　要：石墨烯及其衍生物具有超高的水通量、特殊的物理化学性质和可调节的层状结构等特点,逐渐成为可用于污水处理的新一代膜材料。氧化石墨烯(GO)膜的层间传输通道可通过人工修饰和调控实现油水乳状液的分离,但过程中会出现污染现象缩短GO膜的使用寿命,需对GO膜进行改性以优化性能。介绍了GO膜的主要制备方法,概述了GO膜的改性方法及油水分离机理,总结和展望了石墨烯及其衍生物未来的发展方向以及面临的挑战。Graphene and its derivatives have gradually become a new generation of membrane materials for wastewater treatment due to their ultra-high water flux,special physicochemical properties and adjustable layered structure.The interlayer transport channels of graphene oxide(GO)membranes can be manually modified and regulated for the separation of oil-water emulsions.However,membrane fouling in the process of oil and water separation will shorten the service life of the membrane,so it is necessary to modify GO membrane for performance optimization.The main preparation methods of GO membranes are introduced,the modification methods of GO films and oil-water separation mechanism are summarized,and the future development direction and challenges of graphene and its derivatives are summarized and prospected.
