▎ 摘　　要

NOVELTY - Preparation of graphene or graphite alkenyl oxide separation membrane comprises depositing sequentially or mixedly aminated multi-layer graphene mixed solution and aminated oligolayer graphene oxide mixed solution on bottom film. USE - The method is preparation of graphene or graphite alkenyl oxide separation membrane (claimed). ADVANTAGE - The method improves stability of graphene or graphite alkenyl oxide separation membrane in aqueous solution by modifying multilayer graphene with amino-containing organic macromolecule polymer and oligolayer graphene oxide by using amino organic molecules. It includes combining aminated multilayer graphene and aminated graphene oxide to improve flux and retention. It is simple. The separation membrane has low cost. The problem on low flux of graphene oxide film in aqueous solution is solved.
