Porous silicone sponges are fabricated by polymerization of organosilanes in the presence of Fe3O4@silica nanoparticles. The sponges feature fast magnetic responsivity, superhydrophobicity/superoleophilicity, high compressibility and stability. The sponges can selectively absorb floating oils on a water surface, heavy oils under water and even emulsified oils.
多孔硅海绵是通过在Fe3O4@二氧化硅纳米颗粒存在下有机硅烷的聚合反应制备而成。这些海绵具有快速磁响应性、超疏水性/超亲油性、高压缩性和稳定性。它们能够选择性地吸收水面上的浮油、水下的重油甚至乳化油。
