▎ 摘　　要

NOVELTY - Super-hydrophobic-oleophobic reduced and oxidized graphene filter membrane is claimed. The filter membrane is prepared by adding graphene oxide, nano-zinc oxide in distilled water, ultrasonically dispersing, then adding dopamine hydrochloride containing dopamine solution, mechanically stirring, then vacuum filtering, filtering the mixed solution and depositing on the mixed cellulose ester film surface, and drying to obtain final product. USE - The filter membrane is useful for separating oil and water (claimed). ADVANTAGE - The filter membrane: has high water permeation selectivity, flux and stability; can effectively separates oil-containing waste water; provides a high-efficiency; and is environmentally friendly.
