Effective oil–water separation is necessary to cope with frequent oil spill accidents, which pose huge risksto the marine ecosystem. Among existing oil–water separation methods, gravitational filtration is themost efficient. When super-wetting materials are used for gravitational filtration, they have the meritof high efficiency but they still have the disadvantages of high price, low eco-friendliness, and complexprocedures. To overcome those problems, we fabricated a stainless steel mesh by a one-step methodvia an annealing process. The annealed mesh achieved both superhydrophilicity and superoleophilicity. For oil–water separation, the annealed mesh, which was pre-wetted by water, demonstrated underwatersuperoleophobicity. Thus, this study confirmed that the proposed system can separate various oily mixtureswith high efficiency (>99 %) and it exhibits underwater anti-oil-fouling.
