▎ 摘　　要

NOVELTY - Graphene oxide film comprises a supporting layer and a selective separation layer. The selective separation layer is composed of multi-layer graphene oxide nano sheet, and the surface of the graphene oxide nano sheet is distributed with metal-organic frame-801 nano particles is located between adjacent graphene oxide nano-sheet, the surface of the selective separation layer is further covered with a hydrophobic decorative layer. The material of the hydrophobic modified layer is polydimethylsiloxane and supporting layer is porous inorganic material or porous polymer material. USE - The graphene oxide film is useful for film distillation desalting (claimed) and in-situ growth porous molecular-semiconductor intercalation. ADVANTAGE - The hydrophobic graphene oxide film has good hydrophobicity, high film flux and salt intercepting rate, and excellent separation performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing hydrophobic graphene oxide film. DESCRIPTION OF DRAWING(S) - The drawing shows a technical schematic diagram of a graphene oxide film.
