▎ 摘　　要

NOVELTY - Coating graphene filter membrane material with enhanced hydrophilicity, comprises performing Michael addition reaction under alkaline conditions, and grafting the polymer P (MeO2MA-co-OEGMA-SH) on the graphene filter membrane material containing dopamine to form a super-hydrophilic graphene filter membrane material. USE - The method is useful for coating graphene filter membrane material with enhanced hydrophilicity. ADVANTAGE - The method: utilizes dopamine hydrothermal reduction of graphene to obtain porous polydopamine-graphene gel; has high oil-water separation efficiency; is simple, easy to implement, and economical; has wide in application range, and broad application prospects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing polymer P (MeO2MA-co-OEGMA-SH) using the enhanced hydrophilic graphene filter membrane material, comprising adding 2-methyl-2 acrylic acid-2(2 methoxyethoxy) ethyl ester, using oligoethylene glycol methyl ether methacrylate as monomers, double (2-(2'-bromoisobutyryloxy)ethyl) disulfide as initiator, cuprous bromide as catalyst, 2,2'-bipyridine as ligand, and P(MEO2MA-co-OEGMA-SS-MEO2MA-co-OEGMA) as copolymer, and using tributylphosphine as a reduction catalyst to break the disulfide bond in the P(MEO2MA-co-OEGMA-SS-MEO2MA-co-OEGMA) copolymer to obtain the polymer P(MeO2MA-co-OEGMA-SH).
