混合基质膜（MMMs）将多孔材料与聚合物基质结合，因二者的互补性和协同作用，MMMs在气体分离研究领域得到了广泛关注。多孔材料的可调节性和多样性赋予了MMMs可扩展的功能和优异的分离性能。为了充分发挥MMMs的潜力，研究人员专注于多孔填料与聚合物基质的合理匹配，以提高MMMs的
界面相容性。在本文中，我们重点介绍了利用不同策略，将金属有机框架（MOFs）或金属有机笼（MOCs）与聚合物基质相结合，以制备MMMs的最新进展，并且进一步讨论了MMMs未来发展所面临的机遇和挑战，这将通过合理的材料设计和选择促进MMMs的发展。

Mixed-matrix membranes (MMMs), which combine porous materials with a polymeric matrix, have gained considerable research interest in the field of gas separation due to their complementary characteristics and cooperative activation. The tailorability and diversity of porous materials grant MMMs extendable functionalities and outstanding separation performance. To achieve the full potential of MMMs, researchers have focused on the rational matching of porous fillers with polymeric matrixes to achieve enhanced compatibility at the interfaces of these materials. In this review, we highlight state-of-the-art advances in combining metal–organic frameworks (MOFs) and metal–organic cages (MOCs) with polymeric matrixes to fabricate MMMs using different strategies. We further discuss the opportunities and challenges presented by the future development of MMMs, with the aim of boosting MMM fabrication with judicious material design and selection.
