▎ 摘  要

NOVELTY - Preparation of silk fibroin/graphene oxide composite modified oil-absorbing sponge comprises washing and drying sponge to obtain pretreated sponge, placing silkworm cocoons in sodium carbonate solution to be boiled to remove sericin, placing in lithium bromide for degumming treatment, dialyzing the obtained solution to obtain aqueous silk fibroin solution, adjusting pH value of graphene oxide solution to 10 using alkaline reagent, adding to silk fibroin solution, ultrasonically mixing to obtain mixed solution A, soaking pretreated sponge in mixed solution A, taking out and drying. USE - The method is used for preparing silk fibroin/graphene oxide composite modified oil-absorbing sponge. ADVANTAGE - The method is green and low-cost. The product has strong regeneration ability; and can be mass-produced.
