In conclusion, we have achieved a functionally integrated device for oil-water separation through a facile immersion and modification process. Superhydrophobic and superoleophilic meshes were fabricated by an immersion process after modified by stearic acid. The as-prepared stainless steel mesh surface exhibits both superhydrophobicity with a WCA of 153 ± 3◦possessing simul-taneous a very low adhesion and superoleophilicity with an OCA of 0◦. Besides, a series of oil/water mixtures, such as chloroform/water, hexane/water, toluene/water,gasoline/water and diesel/water, were observed to be separated by the mesh, the separation efficiency of more than 93%. And it remained an excellent efficiency even after 10 cycles. Furthermore, the as-prepared superhydrophobic mesh shows chemical stability in the air environment and corrosion environment. Thus, as-prepared functionalized meshes are expected to become sustainable and highly effective materials for oil-water separation, as the materials can be recycled many times with remarkable durability. Webelieve such selectively separating materials can be used in a lot of applications, such as waste water treatment.
