▎ 摘  要

NOVELTY - Preparing reducing graphene oxide emulsion separation film comprises (i) mixing graphene oxide, reducing agent and buffer solution to obtain reaction solution and (ii) successively washing reaction solution, carrying out vacuum suction filtration and drying. USE - The reducing graphene oxide emulsion separation film is useful for separating oil and water (claimed). ADVANTAGE - The method is simple, saves time and energy and suitable for industrial production. The film is reusable, self-supporting, non toxic, resistant to acid, weak base and high salt environment; has super-hydrophilic/underwater super lipophobic special wetting properties and good stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for reducing graphene oxide emulsion separation film, prepared by above method.
