| titleOfInvention | Preparation method and application of organic-inorganic mixed matrix membrane doped with zeolite imidazole ester framework porous carbon nano material |
| abstract | The invention discloses a preparation method and application of an organic-inorganic mixed matrix membrane doped with zeolite imidazole ester framework porous carbon nano material, wherein the preparation method comprises the following steps: preparing a nickel-containing zeolite imidazole material by a solvothermal method by using zinc nitrate hexahydrate, nickel nitrate hexahydrate and 2-methylimidazole as raw materials; then, calcining the nickel-doped zeolite imidazole ester material serving as a precursor at high temperature of 700-1000 ℃ to prepare a zeolite imidazole ester framework porous carbon nano material; dispersing the porous carbon nano material in a polyether copolyamide solution to prepare a uniform membrane casting solution, wherein the wet membrane thickness is 50-500 mu m, and preparing the mixed matrix membrane doped with the zeolite imidazole ester skeleton porous carbon nano material by a solvent volatilization method. The inorganic material of the invention is simple and easy to obtain, the membrane preparation method is easy to operate, and the mixed matrix membrane is used for CO 2 The separated and added inorganic material can effectively improve the CO of the polyether copolyamide film 2 Permeability coefficient and CO 2 /N 2 A separation factor. |
