摘　　要：MXene纳米片材料因其二维结构特性和丰富的表面基团而受到广泛关注。MXene纳米片组装成的二维层状膜,通过尺寸筛分效应和静电相互作用可实现溶液中小分子和离子等分离,在水处理领域有着巨大的应用潜力。然而,二维层状MXene膜仍然面临着严峻的挑战,如低稳定性、高内阻、水环境中易溶胀等,导致分离性能不理想。本文以层状MXene膜的分离机理为出发点,重点介绍了目前改善层状MXene膜分离性能的方法及研究进展,并对二维MXene膜水处理应用发展进行展望,期望对基于MXene膜的精密构筑和设计高性能分离膜提供有益参考。MXene nanosheet materials have attracted wide attention due to their two-dimensional structural characteristics and abundant surface groups.The assembled two-dimensional MXene lamellar membranes can realize the separation of small and medium molecules and ions in solution through the sieving effect and electrostatic interaction,which has great potential for application in water treatment.However,the twodimensional layered MXene membranes still faces some serious challenges,such as low stability,high internal resistance,easy swelling in water environment,resulting in unsatisfactory separation performance.Based on the separation mechanism of layered MXene membranes,this paper summarizes the methods and research progress to improve the separation performance of layered MXene membranes,and prospects the application development of two-dimensional MXene membranes for water treatment.It is expected to provide a useful reference for the precise construction and design of high-performance separation membranes based on MXene membranes.
