▎ 摘　　要

NOVELTY - Preparing a modified separation membrane of oxidation graphene based on electrostatic spray, involves mixing the oxidized graphene, plant polyphenol, dispersant, and ultrasonically dispersing to obtain an oxidation-graphene-plant polyphenolic dispersion. The oxidizing graphene-plant polyphenols dispersion is sprayed to any surface hydrophobic basement membrane by electrostatic spraying method. The polyethyleneimine is used to cross-link the hydrophilic base membrane to obtain the oxidization graphene modified separation film, where the spraying and the crosslinking treatment are carried out on the same surface of the water-based membrane. USE - Method for preparing of a modified separation membrane of oxidation graphene based on electrostatic spray, which is useful in film distillation industry development (claimed). ADVANTAGE - The method only modifies one surface of the hydrophobically-hydrophobic base film, and the other side does not process, ensuring hydrophoilic transmission layer needed in the film distillation process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an oxidized graphene modified separation membrane obtained by the method preparation to any one of claims to.
