▎ 摘　　要

NOVELTY - Preparing fluorinated graphene-based superhydrophobic separation membrane, comprises forming a layer of flake copper sulfide on the surface of the copper mesh by hydrothermal method, preparing nickel hydroxide/copper sulfide composite material with a rough surface nickel chloride solution by dipping method, and performing interfacial electrochemical polymerization on the surface of nickel hydroxide/copper sulfide composite material to obtain a superhydrophobic oil-water separation membrane with corrosion resistance and self-cleaning properties. The concentration of sodium sulfide solution is 0.1-0.5 mol/l. The pH is adjusted to 5.5-8 with 0.1 mol/l sodium hydroxide aqueous solution. USE - The method is useful for preparing fluorinated graphene-based superhydrophobic separation membrane in oil-water separation (all claimed). ADVANTAGE - The membrane: has simple preparation method, controllable process, corrosion resistance and superhydrophobicity; separates oily wastewater efficiently; and can be reused at the same time.
