NOVELTY - Preparing polymer-modified graphene filter membrane involves coating polydopamine on the surface of the cleaned stainless steel mesh, reacting the stainless steel mesh coated with polydopamine and graphene oxide to prepare a graphene oxide/polydopamine coated stainless steel mesh. The polymer P(MeO2MA-co-OEGMA-SH) with mercapto groups at the end is grafted onto the graphene oxide/polypolymer prepared under alkaline conditions, by Michael addition reaction. The ssuper-hydrophilic polymer-modified graphene filter membrane is prepared on a stainless steel mesh coated with dopamine. USE - Method for preparing polymer-modified graphene filter membrane. ADVANTAGE - The method enables to prepare polymer-modified graphene filter membrane has high mechanical strength, good mechanical capability, long using life, in simple and cost-effective manner.
