摘要 The ability to regulate and apply surface wettability has attracted much attention in the surface engineering field.In this study,a simple chemical etching method was used to construct a rough micro/nano structure on 304 stainless steel mesh;this rough surface was subsequently decorated with fatty acids of varying chain length to regulate wettability.The wettability,composition,and morphology of the surface were characterized and ana-lyzed by measuring contact angles,and by atomic force microscopy,scanning electron microscopy,and Fourier-transform infrared spectroscopy.The superhydrophobic and superoleophilic properties of the mesh modified with long-chain fatty acids were examined for oil-water separation performance and reusability.The surface had a micro/nano hierarchical morphology with ordered carbon chains,and the hydrophilic-to-superhydrophobic transformation was achieved by adjusting the chain length of the fatty acid to deliver contact angles in the range of 30°~154°.The oil contact angle was always 0°,irrespective of the chain length fatty acid,and oil drops quickly penetrated the mesh surface.A fatty acid with a longer chain afforded a more hydrophobic and oleophilic mesh surface and better oil-water separation efficiency(up to 96%),which still exceeded 85%after 50 cycles of oil-water separation testing.Consequently,the prepared surface with controllable wettability has excellent prospects for use in intelligent response interfaces and oil-water separation applications.
