A preparation method and application of an MOF/polymer composite membrane belong to the field of membrane separation. The invention adopts a polymer substrate as a supporting layer, uses an ionic polymer with opposite charges to MOF, and prepares a composite membrane with good stability through electrostatic interaction. Meanwhile, the MOF and the polymer have good dispersibility in water, so that the compatibility of the MOF and the polymer can be improved, and an MOF/polymer composite membrane which is environment-friendly, uniform, compact, high in loading capacity and high in stability is prepared by using a spin coating method and is used for removing dye in the field of nanofiltration. The method is environment-friendly, simple and feasible, has relatively low cost, has a good separation effect on dye removal, and has potential application value. |
