摘　　要：从石墨烯基分离膜的结构和功能角度出发,阐述了纳米孔石墨烯分离膜、氧化石墨烯(GO)片层堆叠分离膜及GO聚合物复合膜的制备方法,分析了该领域面临的问题及应用前景,石墨烯及其衍生物具有特殊的选择分离特性,是制备新一代水处理膜的研究热点。认为现有制备工艺仍然存在不足和缺陷,设计和调控纳米孔道是实现低污染、高通量的重要手段,在实现大规模制备的同时保证膜的分离性能、如何从绿色的角度出发制备复合膜,是未来的研究方向。From the perspective of the structure and function of graphene-based separation membrane, the preparation methods of nanoporous graphene-based separation membranes, graphene oxide sheet stack separation membranes and graphene oxide polymer composite membranes were discussed, the problems and application prospects in this field were analyzed. Graphene and its derivatives have special selective separation properties,which is a research hotspot in the preparation of a new generation of water treatment membranes. It is believed that the existing preparation process still has shortcomings and defects, and the design and control of nanopore channels is an important means to achieve low pollution and high throughput. It is the future research direction to ensure the separation performance of the membrane while achieving large-scale preparation, and to prepare composite membranes from a green perspective.
