▎ 摘  要

NOVELTY - Preparing modified graphene oil-water separation foam material comprises (1) dissolving the microcrystalline cellulose in water, ultrasonically dispersing, obtaining mixed solution I, (2) soaking the porous foam material in the mixed solution I, taking out and drying, (3) soaking the material obtained in the step (2) in the water solution of the modified graphene, and taking out and drying to obtain the modified graphene oil-water separating foam material. USE - The method is useful for preparing modified graphene oil-water separation foam material. ADVANTAGE - The method: increases the adsorption amount of graphene, so as to improve the adsorption performance of modified graphene oil-water separation foam material.
