NOVELTY - Preparation of polymer/graphene oxide composite separation membrane involves adding graphene oxide to water, ultrasonically dispersing for 1-3 hours to form 0.5-10 g/L graphene oxide aqueous solution as a coagulation bath, mixing polymer, solvent and additive, stirring at 40-60 degrees C, defoaming to obtain polymer casting solution, solidifying the casting solution in coagulation bath for 30-1200 seconds, removing membrane from coagulation bath, and washing using deionized water for 0.5-24 hours. USE - Preparation of polymer/graphene oxide composite separation membrane (claimed). ADVANTAGE - The method enables manufacture of polymer/graphene oxide composite separation membrane with excellent workability by simple method.
