In this work, a modified preparation procedure is proposed to fabricate silica-type films on stainless steel mesh surface with improved chemical bonds for special wettability in virtue of advisably using bis-silane via self-assembled technique, modified St(o)ber and dip-coating approaches. For one thing, bis-silane was chemically anchored onto stainless steel surface to introduce a considerable amount of silicon hydroxy groups by self-assembled technique. For another, bis-silane was added into St(o)ber solution to hydroxylate silica nanoparticles (SiO2 NPs). Upon dip-coating in the modified St(o)ber solution, stainless steel mesh could easily chemically bond with hydroxylated SiO2 NPs, forming a hierarchical silica-type film with superamphiphilic ability both in air and underwater. After modified with long-chain perfluorodecyltrichlorosilane (PFDTCS), the superamphiphilic surface turns into be superhydrophobic and superoleophylic, capable of separating oil-water mixture with good recyclability. The superhydrophobic mesh also possesses excellent chemical durability and stability under harsh surroundings.
