Current MOF composite membranes usually suffer from unduly thick MOF layers and poor adhesion with the polymer substrate. We prepared a thin MOF film (440 nm) on a polymer support with 2-D MOF nanosheets as seeds via a layer-by-layer growth. These 2-D MOF seeds not only provided bonding between the MOF film and the polymer substrate but also facilitated the formation of a continuous and defect-free MOF membrane, which demonstrated excellent performance in gas separation.
当前的金属有机框架（MOF）复合膜通常存在MOF层过厚以及与聚合物基材附着力差的问题。我们通过逐层生长的方法，以二维MOF纳米片为种子，在聚合物载体上制备了一层薄的MOF薄膜（440纳米）。这些二维MOF种子不仅在MOF薄膜和聚合物基材之间提供了结合力，还促进了连续且无缺陷的MOF膜的形成，该膜在气体分离方面表现出优异的性能。
