Superhydrophobic stainless steel mesh was prepared by using epoxy resin to bondthe stearic acidmodified fly ash on the surface of stainless steel mesh skeleton. The as-prepared mesh was characterized by TEM, SEM, FTIR, and contact angle measurement. Theresults showed the surface of the modified super hydrophobic stainless steel mesh under high power microscope exhibited a micro-nanohierarchicalstructure with a certain roughness, and the water contact angle of the mess was up to 153°. In addition,the as-prepared stainless steel mesh had good mechanical stability and superhydrophobic durability. The water contact angle of the surface was still as high as 141° after 100 mechanical abrasiontests. The material was used in the separation of various oil/organic solvents and water mixtures, and the separation efficiency wasall higher than 94%.
