▎ 摘  要

NOVELTY - Preparation of titanium dioxide/graphene oxide/stearic acid composite modified sponge comprises taking sponge, respectively soaking in pure water and anhydrous ethanol, ultrasonically treating, drying to obtain preprocessed sponge, taking graphene oxide dispersion liquid, diluting with anhydrous thanol, obtaining graphene oxide solution, adding titanium dioxide powder into graphene oxide solution, adding magnesium stearate, ultrasonically treating to obtain mixed solution, soaking the preprocessed sponge in the mixed solution, ultrasonically treating and drying. USE - The method is for preparation of titanium dioxide/graphene oxide/stearic acid composite modified sponge. ADVANTAGE - The method is simple and provides composite modified sponge, which has hydrophobic oil absorption property and can be produced on a large scale.
