Therefore, the super-lyophobic surface material is expected to be widely applied to the fields of buildings, traffic, chemical engineering, medical treatment, agriculture, oceans, petroleum and the like due to the advantages of self-cleaning, pollution prevention, corrosion prevention, ice prevention, fluid drag reduction, oil-water separation and the like.
However, in the ever-expanding market volume of surface engineering in the trillions per year, the contribution of ultralyophobic surface materials is extremely low, and can only be commercially applied in certain specific scenes in certain limited fields, which makes it difficult to apply widely in life scenes and industrial situations. The main reason for this is that the engineered ultralyophobic surface material is mainly composed of nano inorganic powder and polymer resin, but the homogeneity between the nano inorganic powder and the polymer resin is low, resulting in high brittleness of the multi-layer structure composed of the nano inorganic powder and the polymer resin, and thus low abrasion resistance and scratch strength of the ultralyophobic surface material. Therefore, the ultralyophobic surface material prepared by the conventional method is difficult to serve for a long time. The Chinese patent with application number 201510175294.6 discloses a preparation method of a super-hydrophobic and oleophobic composite coating, but the method adopts a double-layer coating construction mode, is complex to operate and is not beneficial to large-format operation, and after fluorinated organic micromolecules are introduced, the super-lyophobic surface material has the problems of easy precipitation, environmental pollution and the like.
