摘要： A method for preparing a sustained release antibacterial film includes: (1) mixing a cyclodextrin metal-organic framework (CD-MOF) material with a silver nitrate short-chain alcohol solution to prepare an intermediate material A; (2) mixing the intermediate material A with a caffeic acid short-chain alcohol solution to prepare an intermediate material B; (3) dispersing the intermediate material B in a solvent, adding a polydimethylsiloxane main agent and a PDMS auxiliary agent in sequence, and mixing well by stirring to obtain a casting solution; and (4) coating the casting solution on a film support material, conducting vacuum drying, and peeling off a film from the film support material to obtain the sustained-release antibacterial film. A mixed matrix-based film material in which the CD-MOF and the PDMS are physically blended is prepared based on CD-MOF and PDMS for the first time, and may be used in application researches of food, environment and other fields.

摘要： Disclosed are a zirconium-based metal-organic framework material and a preparation method thereof. Plasma-activated water or strong acid electrolyzed water is added to a raw material system for preparing a zirconium-based metal-organic framework material UiO-66, and they are then subjected to a reaction to obtain a crude product. The crude product is subjected to a post-treatment to obtain the zirconium-based metal-organic framework material UiO-66.

摘要： Disclosed are a caffeic acid-based composite material and a preparation method thereof. The method includes: exposing a cyclodextrin metal-organic framework material prepared from γ-cyclodextrin to a solution of caffeic acid in a short-chain alcohol to obtain a mixed material; and incubating the mixed material, wherein during the incubating, the cyclodextrin metal-organic framework material is in dynamic contact with the solution of caffeic acid in a short-chain alcohol. The prepared composite material includes a cyclodextrin metal-organic framework material and caffeic acid loaded on the cyclodextrin metal-organic framework material, wherein the cyclodextrin metal-organic framework material is prepared from γ-cyclodextrin. The caffeic acid is loaded in an amount of 15-18% of a total mass of the caffeic acid-based composite material. The caffeic acid is located in a cavity of the cyclodextrin metal-organic framework material.
