The invention provides a metal organic framework material-containing composite film and a preparation method, which are composed of the following components in parts by weight: 5-20 parts of polyvinylidene fluoride, 10-35 parts of dimethylformamide, and 3 parts of metal organic framework material. ~15 parts; the dimethylformamide of the present invention contains small solvent molecules, and after heating, the small solvent molecules can be removed to expose unsaturated metal sites, and these unsaturated metal sites can adsorb pollutants in the dye; As a polymer material, polyvinylidene fluoride is difficult to dissolve, and dimethylformamide can also be used to dissolve polyvinylidene fluoride, so that the metal organic frame material and polyvinylidene fluoride can fully dissolve and react; the device of the invention is simple and easy to operate. ,high productivity. |
