NOVELTY - A two-dimensional hybrid material comprises graphene oxide surface modified functional porous polymer. USE - Two-dimensional hybrid material for filter material used in pollutant detection and adsorption separation, pollution adsorption and separation (all claimed). ADVANTAGE - The two-dimensional hybrid material has both structural and functional characteristics of two-dimensional graphene oxide and functional porous organic polymer. When assembling into water filter layer, the material has high water permeability, and efficient pollutant removal performance and also provides an integrated solution for simultaneous detection and separation of pollutants. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of two dimensional hybrid material porous polymer, which involves (1) dripping 4-chloromethylstyrene and cross linking agent into aqueous solution containing graphene oxide, raising temperature at to 60-80 degrees C, adding initiator, refluxing reaction under an inert atmosphere for 4-8 hours, washing mixed solution obtained with an ethanol and/or water, centrifuging, and freeze-drying to obtain intermediate product (A), (2) adding intermediate product (A) and to glacial acetic acid, stirring well, adding crosslinking agent (A1) and catalyst (C1), reacting at 70-90 degrees C for 2-4 hours, adding acetone/hydrochloric acid /water mixed solvent to stop the reaction, filtering, washing, freeze-drying to obtain intermediate product (B), (3) dispersing intermediate product (B) in solvent (S1), swelling overnight, adding catalyst (C2) at 65-85 degrees C, stirring reaction mixture for 12-46 hours, adding a mixed solvent of acetone/hydrochloric acid/water to stop the reaction, filtering, washing, and freeze-drying to obtain intermediate product (C) is obtained, and (4) mixing intermediate product (C) with N-(2-aminoethyl) carbazole, cesium carbonate, and anhydrous dimethylformamide, stirring continuously at room temperature for 16-32 hours in dark, washing with dimethylformamide, and water, performing centrifugal separation, and freeze-drying; and (2) filter material, which is prepared by dispersing multifunctional two-dimensional hybrid material in solvent, and using microporous filter membrane as supporting membrane.
