▎ 摘　　要

NOVELTY - Composite material comprises a core-shell structure, a core layer is a porous material, and a shell layer is a high molecular polymer. The porous material comprises metal-organic frameworks, porous oxides, zeolites and/or activated carbon. USE - The composite material is useful in the fields of catalysis, gas adsorption and separation (claimed). ADVANTAGE - The composite material provides a porous material wrapped with high molecular polymer; ensures that the surface high molecular polymer will not cause the porous material to lose its own properties e.g. crystallinity and pore properties; improves mechanical stability and chemical stability and ensures that the polymer is wrapped on the surface of the porous material by heterogeneous deposition. The method is fast and has high and uniform coating rate at high scores. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing composite material comprising (a) mixing the porous material and the high molecular polymer in the good solvent of the macromolecule to realize the coating and (b) adding the poor solvent of the macromolecule, separating out and separating the precipitate to obtain the composite material.
