NOVELTY - A separation membrane comprises a polymer support layer, and a coating layer comprising graphene oxide in at least one base resin chosen from polysulfone, polyethersulfone, polyvinylidene fluoride, polyacrylonitrile, polytetrafluoroethylene and polypropylene, formed on a surface of the polymer support layer. The coating solution for forming coating layer comprises 6-10 wt.% graphene oxide, and 1-10 pts. wt. at least one adhesion promoter e.g. polyoxyethylene alkylaryl ether, sorbitan fatty acid ester, polyoxyethylene alkyl ester, polyoxyethylene alkylamine, alkylester, alkyl phosphate, alkyl sulfosuccinate, and alkyldimethylbenzyl ammonium chloride, and 10-50 pts. wt. at least one polyfunctional compound e.g. polypropylene glycol (meth)acrylate, cyclohexanedimethanol di(meth)acrylate, tricyclodecanedimethanol diacrylate, trimethylolpropane tri(meth)acrylate, pentaerythritol tri(meth)acrylate, pentaerythritol tetra(meth)acrylate and trimethylolpropane triacrylate. USE - Separation membrane is used for water treatment. ADVANTAGE - The separation membrane can improve treatment efficiency and throughput of sewage and wastewater by inducing improvement in performance and permeation.
