▎ 摘　　要

NOVELTY - Preparation of graphene oil-absorbing sponge, involves adding graphene oxide powder to water and ultrasonically dispersing to obtain an aqueous graphene oxide solution, adding a modifier to the aqueous graphene oxide solution, heating after stirring, and grafting the graphene oxide, soaking the sponge in the modified graphene oxide solution and removing the sponge soaked in the graphene oxide solution, and reducing high temperature and drying. USE - Preparation of graphene oil-absorbing sponge for use in application of water pollutant removal, oil exploitation and separation of industrial oil pollutants. ADVANTAGE - The graphene oil-absorbing sponge has function of sucking oil and not absorbing water, and the oil absorption amount reaches several hundred times of own weight, and the adsorbed oil product can be recovered by simple extrusion. The graphene oil-absorbing sponge has low cost, simple operation and excellent reusability.
