摘要:

相较于传统聚酰胺薄层复合(TFC)膜,金属有机骨架/聚酰胺薄层纳米复合(TFN)膜得益于MOFs材料的高比表面积、有序可控的孔隙结构、良好的聚合物相容性和可定制的化学功能,展现出更高的渗透选择性,在工业应用中显示出巨大的分子和离子分离潜力。本文首先简述了MOFs聚酰胺复合膜的研究背景,然后从MOFs材料的特性和MOFs聚酰胺复合膜的制备策略两个方面出发,总结了MOFs聚酰胺膜研究的最新进展。讨论了MOFs的物化特征在TFN膜的微观结构和分离性能中起的作用;介绍了MOFs聚酰胺复合膜的制备策略,重点对MOFs负载方法及效率进行了分析。最后简述了MOFs聚酰胺复合膜在气、液体系分离中的应用;对MOFs聚酰胺膜在应用过程中的稳定性问题进行了分析,并对未来MOFs聚酰胺复合膜优化MOFs负载和功能性设计的研究进行了展望。

Abstract:

Compared to the traditional polyamide thin-film composite (TFC) membranes, metal-organic frameworks (MOFs)/polyamide thin-film nanocomposite (TFN) membranes exhibit higher perm-selectivity and show great potential for molecular and ion separation in industrial applications, which benefited from MOFs materials with high surface area, orderly and controllable pore structure, favored polymer affinity and customizable chemical function. This review first briefly introduced the research background of MOFs polyamide composite membrane, and then summarized the progress of MOFs polyamide composite membrane in terms of the characteristics of MOFs materials and the preparation strategy of MOFs polyamide composite membrane. The roles of physicochemical features of MOFs in the microstructure and separation performance of TFN membranes are discussed. Subsequently, various preparation strategies of MOFs doped polyamide membrane are introduced, and the loading efficiency of MOFs is analyzed. Finally, the application of MOFs polyamide composite membrane in gas and liquid system separation is briefly described. The stability of MOFs polyamide membrane in the application process is analyzed, and the future research of MOFs polyamide composite membrane in the optimization of MOFs load and functional design is prospected.

Key words: metal-organic frameworks (MOFs), thin-film nanocomposite membranes, preparation strategies, membrane separation
