Problems solved by technology

[0003] In the prior art, there are many methods for manufacturing super-hydrophobic surfaces, and many super-hydrophobic surfaces have come out. However, most of them are still in the experimental stage. In theory, there is a problem of inconvenient use, which will greatly increase the cost of use. Realizing large-scale application of superhydrophobic surfaces
At the same time, the preparation cost is relatively high, and the mechanical strength of the prepared superhydrophobic surface is not high, which cannot meet the actual needs.

Abstract

The invention discloses a super-hydrophobic glue film comprising a super-hydrophobic film with a super-hydrophobic surface. The super-hydrophobic glue film is characterized in that the non-super-hydrophobic surface of the super-hydrophobic film is provided with an adhesive glue layer. When in use, the super-hydrophobic film can be stuck on any surface. The invention has the advantages of convenient use, simple structure, easy production, high strength, low cost and capability of scale production and application.

Description

technical field [0001] The invention relates to a superhydrophobic structure, in particular to a superhydrophobic adhesive film. Background technique [0002] Surface wettability is an important property that determines the application of materials. Many physical and chemical processes, such as adsorption, lubrication, adhesion, dispersion, and friction, are closely related to surface wettability. Research on superhydrophobic surfaces has attracted great attention due to their potential applications in self-cleaning surfaces, microfluidic systems, and biocompatibility. The so-called super-hydrophobic surface generally refers to the contact angle with water greater than 150 and less than 10. The rolling angle of water droplets is excellent, and it has the functions of waterproof, anti-icing, anti-fog, anti-snow, anti-fouling, anti-dust, and prevention of corona noise caused by water droplets on power transmission lines. Therefore, it has broad application prospects in the f...
