▎ 摘　　要

NOVELTY - Preparing oil-absorbing sponge modified based on graphene oxide, comprises (i) cleaning polyurethane sponge with ethanol, soaking in 0.1 wt.% graphene oxide solution and drying; (ii) mixing uniformly using n-hexane as a solvent and 1.0 wt.% methyltrichlorosilane as a functional material to obtain a modified solution, and soaking the polyurethane sponge soaked in the graphene oxide solution into the modification solution for the soaking time t, where t≥ 1 minute; and (iii) taking out soaked the sponge and drying. USE - The method is useful for preparing oil-absorbing sponge modified based on graphene oxide. ADVANTAGE - The method uses methyltrichlorosilane as a functional material to be dissolved in n-hexane, and the polyurethane sponge loaded with graphene oxide is soaked to produce polysiloxane covering the surface of the sponge, thus greatly improving the hydrophobic and oil absorption effect of the sponge. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating the method for preparing oil-absorbing sponge modified based on graphene oxide (Drawing includes non-English language text).
