Description

technical field [0001] The invention relates to the field of preparation of metal-organic framework membranes (MOFs membranes), in particular to a method for preparing metal-organic framework membranes on polymer base membranes. Background technique Metal-organic framework compounds (hereinafter referred to as "MOFs") are metal-organic framework compounds with a certain skeleton structure formed by the coordination of metal ions and organic ligands. Applications in optics and catalysis have attracted more and more attention. In the past few years, researchers have mainly devoted themselves to the research on methods of using multifunctional organic ligands and highly functional metal ions to obtain novel structures of MOFs and using carrier substrates to grow MOFs membranes. Due to the wider potential applications of MOFs membranes, researchers are interested in obtaining uniform, defect-free and continuous MOFs membranes. However, in order to obtain a uniform, defect-f...
