NOVELTY - Preparing self-foaming graphene oxide/polydimethylsiloxane sponge involves dissolving amino-terminated polydimethylsiloxane in an organic solvent, adding graphene oxide, evenly stirring, adding condensing agent and glutaraldehyde, continuously stirring, transferring the mixed liquid to a mold, and curing. USE - The method is useful for preparing sponge used in oil-water separation. ADVANTAGE - The method enables simple preparation of sponge under mild reaction condition, with excellent lipophilicity, and mechanical property, stable structure, and multiple cyclic regeneration realized by using physical compression method.
