Wettability is also the importance in Materials science and Surface Engineering field simultaneously, in daily life, industrial production, has many important application in agriculture production.So-called super-hydrophobicly refers to that the static contact angle of water droplet at solid surface is more than 150 °, in like manner, super oleophobic and oil droplet at the static contact angle of solid surface more than 150 °.But the surface tension of oil droplet is much smaller than the surface tension of water droplet, and therefore, prepare the solid surface with super oleophobic property, its difficulty is larger than super hydrophobic surface, more difficult realization.Correlative study shows, prepare super oleophobic surface in air and, except needing the modification of low surface energy molecule, also micro-nano coarse structure will be with to introduce recessed surface curvature on the surface at it, make micro-nano coarse structure be indent or cantilever.
At present, a large amount of documents has reported artificial bionic super hydrophobic surface, and these materials are at self-cleaning surface, anti-icing, antifog, anti-pollution, and anticorrosive metal is widely used in fluid drag-reduction.Report about oleophobic surface is relatively less, but super oleophobic surface such as grease proofness coating in industrial and agricultural production, the antifouling process of seawater, petroleum pipe line is grease proofing creeps, and has huge application space in oily water separation.Metallic substance is widely applied in engineering, use face extremely extensive, but the antipollution Corrosion Protection of metal is poor, and therefore on metal, preparation has super oleophobic property surface and is significant.
So-called Surface Texture (Surfacetexture) refers to that body surface has the array of the patterns such as the pit of certain size and arrangement, indenture or convex closure.The surface with micro-nano-scale microcosmic texture shows distinct feature with smooth surface in surface energy, optical characteristics, bionical characteristic, mechanical characteristics, hydrodynamic characteristics and friction and wear behavior etc., this is filled with new vitality for numerous disciplinary study, and shows huge application potential at many engineering fields.
The preparation method of oleophobic surface follows from bottom to top or top-to-bottom method usually.The processing method that existing preparation surpasses oleophobic surface mainly contains following several: (1) nothing/have template wet etching (2) femtosecond laser etching method (3) method of electrostatic spinning (4) electrodip process (5) sol-gel method etc.Super hydrophobic surface or the morphology controllable of acquisition are poor, and etching technics is complicated, use material to be only limitted to silicon materials; Or process efficiency is low, be not suitable for extensive manufacture, and equipment is extremely expensive; Or shaping difficulty is large, and surperficial mechanical mechanics property is poor, does not possess good wear resistance.
