The invention relates to a preparation method of an antibacterial
metal-organic framework membrane. The technical scheme of the method is that an organic molecule modification layer is pre-grown on the surface of a carrier, such that the carrier with an organic molecule
coating is obtained; the
organic molecules have coordination active groups, and can induce
metal ions to coordinate with them; the
metal ions are further assembled with the organic ligand, such that a continuous and dense metal-organic framework membrane is formed through growth. According to the invention, the metal-organic framework membrane is grown on the organic-molecule-modified carrier, such that the problems of insufficient
binding force between the membrane and the carrier, poor
weather resistance and poor
heat resistance can be solved. Also, with the coordination effect of the organic ligand and the metal ions, metal
ion release concentration and speed can be effectively controlled, such that a long-lasting
antibacterial effect can be achieved. With the method provided by the invention, the quality of the metal-organic framework membrane is improved; the preparation process is simple; and the prepared antibacterial membrane can be widely applied in the aspects of
aerospace equipment,
medical equipment, product packaging, anti-bacterial
coating,
water treatment membrane, and the like. The membrane and the preparation method have a good application prospect.
