▎ 摘　　要

NOVELTY - Preparation of seawater desalination film, i.e. modified graphene oxide composite film comprises modifying graphene oxide with three different structured diamine monomers, regulating interlayer spacing of nanosheets to prevent interlayer expansion of graphene oxide in water, and self-assembling on mixed cellulose film or cellulose acetate film. USE - The method is for preparation of seawater desalination film, i.e. modified graphene oxide composite film. ADVANTAGE - The film has high salt rejection rate and high flow capacity.
