用于气体分离的含多孔材料的混合基质膜--从金属有机框架到离散分子笼

Mixed-Matrix Membranes Containing Porous Materials for Gas Separation:From Metal-Organic Frameworks to Discrete Molecular Cages

混合基质膜(MMMs)将多孔材料与聚合物基质相结合,因其互补特性和协同激活已经在气体分离领域引起了相当大的研究兴趣。多孔材料的可塑性和多样性赋予MMMs可延伸的功能和出色的分离性能。为了发挥MMMs的全部潜力,研究人员关注多孔填料与聚合物基质的合理匹配,以实现这些材料之间界面的增强相容性。在本文中,我们重点介绍采用不同策略将金属-有机框架(MOFs)和金属-有机笼(MOCs)与聚合物基质相结合制备MMMs的最新进展。文中进一步讨论未来MMMs发展所面临的机遇和挑战,并旨在通过合理的材料设计和选择推动MMMs的制备。

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 stateof-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 boostingMMMfabrication with judicious material design and selection.
