Description
Technical Field
The invention belongs to the technical field of hydrophobic coatings, relates to a silicon oxide-based super-hydrophobic coating and also relates to a preparation method of the silicon oxide-based super-hydrophobic coating.
Background
The superhydrophobic surface has a water contact angle greater than 150 ° and a low roll off angle (less than 10 °). The method for realizing the super-hydrophobicity comprises the following steps: vertical array nanotubes and nanofibers, sol-gel method (sol-gel), phase separation method, layer-by-layer self-assembly (LBL), grazing angle deposition, and the like. Among these techniques, the sol-gel method is simpler and more efficient than other methods in the technique of depositing a superhydrophobic coating, and at the same time, it has significant advantages in that it can coat a large area, the surface shape of the deposited object is not limited, and the coating time is short. Two major factors affecting the wettability of a solid surface are the surface chemical composition (surface free energy) and the surface topography (roughness), respectively. Superhydrophobicity is the result of a combination of specific roughness structures and low surface energy materials. To achieve superhydrophobicity, a rough surface may be obtained first, followed by a low surface energy, or a rough structure with low surface energy may be achieved at the same time.
The contact area of solid and liquid is reduced due to the rough structure of the super-hydrophobic surface, and meanwhile, the contact area of the surface and pollutants is small, so that the acting force between the surface and the pollutants is weakened; when the liquid drops roll, the pollutants on the super-hydrophobic surface are easily taken away, and the unique self-cleaning property enables the super-hydrophobic liquid drops to have wide application prospects in industrial and agricultural production, national defense construction and daily life.
