水污染是一个重大的全球挑战，因为传统的聚合物膜已不足以进行水处理。在用于水处理的新兴材料中，复合膜很有前景，因为它们同时改善了水的渗透性和离子截留率。最近，一种称为 MXenes 的新型 2D 材料因其吸引人的特性和广泛的应用而引起了广泛的关注。由于其高兼容性，MXene 可以融入许多聚合物材料中。人们发现，由于 MXene 的聚合物链和表面官能团之间的强烈相互作用以及所产生的选择性纳米通道，MXene / 聚合物复合膜具有吸引人的电、热、机械和传输性能。本文回顾了用于水净化的离子选择性 MXene 膜领域取得的进展。它透视了进展并提供了前景。简要描述了 MXenes 的性质和合成方法。综述了 MXene 基膜的制备策略，包括混合基质膜、薄膜纳米复合膜和层压膜。阐明了基于 MXene 的离子分离和水淡化膜的最新进展。阐明了膜的离子分离性能对制造技术、MXene 的层间距和 MXene 的各种表面终端的依赖性。最后，讨论了基于 MXene 的离子选择性膜的机遇和挑战。
Water pollution is a major global challenge, as conventional polymeric membranes are not adequate for water treatment anymore. Among emerging materials for water treatment, composite membranes are promising, as they have simultaneously improved water permeation and ions rejection. Recently, a new family of 2D materials called MXenes has attracted considerable attention due to their appealing properties and wide applications. MXenes can be incorporated into many polymeric materials due to their high compatibility. MXenes/polymer composite membranes have been found to have appealing electrical, thermal, mechanical, and transport properties, because of strong interactions between polymer chains and surface functional groups of MXenes and the selective nanochannels that are created. This article reviews advances made in the area of ion‐selective MXene‐based membranes for water purification. It puts the advances into perspective and provides prospects. MXenes’ properties and synthesis methods are briefly described. Strategies for the preparation of MXene‐based membranes including mixed‐matrix membranes, thin‐film nanocomposite membranes, and laminated membranes are reviewed. Recent advances in ion‐separation and water‐desalination MXene‐based membranes are elucidated. The dependence of ion‐separation performance of the membranes on fabrication techniques, MXene's interlayer spacing, and MXene's various surface terminations are elucidated. Finally, opportunities and challenges in ion‐selective MXene‐based membranes are discussed.
