| titleOfInvention | A new type of Polymer-COF-MOF composite membrane and its preparation method |
| abstract | The invention discloses an in-situ growth-based Polymer-COF-MOF composite film and a preparation method thereof. The Polymer-COF-MOF composite film has a stacked multilayer film structure, and is firstly formed by copolymerization of COF ligands and linear Polymer to form a polymer The polymer-COF-MOF composite membrane was prepared by placing the polymer-COF-MOF composite membrane in the metal center ion precursor solution, adding the organic ligand solution with amino group and stirring it evenly. ; During the formation of the MOF film layer, the metal central ion of the MOF film layer forms a coordination bond with the organic ligand, and the amino group on the organic ligand reacts with the carboxyl group or the residual aldehyde group of the Poly-COF film layer, Realize the in-situ growth of the MOF film layer on the COF film layer; in the Polymer-COF-MOF multi-layer composite film provided by the present invention, the polymer and the COF film layer are chemically bonded through covalent bonds; The connection is realized by the amide bond (or Schiff base) generated by the reaction between the carboxylic acid (or aldehyde group) and the amino group, and the structure is stable and the mechanical strength is higher. |
