摘要：

层层堆叠的石墨烯分离膜，由于具有独特的物理化学性质和可调的二维层状结构等特性，能实现不同物质的分离，在脱盐、水处理、离子筛分、气体分离等领域倍受青睐。本文综述了近年来石墨烯膜在分离领域中研究新进展，简要概述了石墨烯膜的制备方法，重点介绍了基于还原法、分子/离子交联法等来提高石墨烯膜在水溶液中的稳定性以及对其层间距进行精确调控的研究现状，最后对石墨烯膜未来的发展方向进行展望，为可控构筑稳定高效分离的石墨烯分离膜提供参考。

Graphene-based membranes with laminar structures exhibit outstanding performances in the separation field due to their unique physicochemical properties and tunable interlayer spacing. Hence, they are widely used in desalination, water treatment, ion sieving or gas separation and so on. The recent developments of graphene-based membranes with laminar structures are reviewed. The fabrication approaches of graphene-based membranes are briefly introduced. Besides, the stability improvements of graphene-based membranes in aqueous environment and controllable regulation of interlayer-spacing based on reduction methods, molecular or ionic cross-linking methods are highlighted, which are of great significance to the researches and applications of laminar graphene-based membranes with stability and high-efficient separation for long-term use in future.
