NOVELTY - Preparation of superhydrophobic superlipophilic modified sponge material comprises preparing fluorinated graphene ethanol dispersion in plastic container, soaking sponge block in fluorinated graphene ethanol dispersion while repeatedly pressing the sponge block to uniformly disperse fluorinated graphene in sponge block, and putting the plastic container in vacuum drying oven at 75-85 degrees C to obtain fluorinated graphene sponge after evaporation of ethanol to dryness; and adding carbon nanotube and sodium carbonate at weight ratio of 1:3-4 to solvent to prepare dispersion, putting the fluorinated graphene sponge in the dispersion while slowly pressing 2-5 times, adding low-surface-energy reagent and reacting at 58-62 degrees C for 11-13 hours, and vacuum drying the sponge block at 55-65 degrees C. USE - The method is for preparing superhydrophobic super-lipophilic modified sponge material used in oil-water separation. ADVANTAGE - The method of is simple and fast, and has low cost. The resulting modified sponge material can quickly absorb different oils and organic solvents on or underwater, and can realize oil recovery and sponge recycling by extrusion deoiling.
