▎ 摘　　要

NOVELTY - Graphite alkenyl sea water desalting film comprises a supporting layer and composite structure unit, where the complex structure unit comprises an oxidation graphene layer and a porous graphene layer, and the supporting layer is located below the composite structural unit. USE - Graphite alkenyl seawater desalting film used in a nanofiltration membrane for water supply and demand. ADVANTAGE - The alkenyl graphite sea water desalting film has high mechanical performance and good durability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the graphite preparation method, which involves: a. using chemical vapor deposition method on the metal substrate preparation porous graphene metal substrate graphene porous sample; b. obtaining the metal substrate porous graphene of the sample of the porous graphene with the polymer and using solvent to soak the interface, then using chemical etching method to remove the metal substrate rinsing dry to obtain the supporting layer porous graphene layer sample; c. depositing a dry oxide layer on surface of the porous layer porous graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of graphite alkenyl sea water desalination film. (Drawing includes non-English language text).
