A simple and inexpensive one-step laser cladding method is reported to make the stainless steel mesh underwater superoleophobic. The micro/nanoscale morphologies were created via cladding a copper foil onto the stainless steel mesh using the nanosecond laser marking system. The fabricated stainless steel mesh has the underwater superoleophobic property with oil contact angles greater than 150 degrees. Based on the special wettability, the fabricated stainless steel mesh is used to separate the light oil-water mixtures, and the separation efficiencies are >98.3%.
