Super-hydrophobic surface refers to a special wettability surface where the contact angle of thedroplet on the surface is greater than 150°. In recent years, those super-hydrophobic surfaces withspecial wettability have caused a research boom due to their unique wetting properties. It hasmany excellent properties such as drag reduction, water resistance, corrosion resistance, etc., andhas high

Superhydrophilicity refers to the high surface energy of a material, which enhances its affinity with water or other polar liquids. On this surface, water droplets are almost unable to slide, but can tightly adhere to the surface. Super hydrophilic materials have advantages in self-cleaning surfaces, preventing water evaporation, and reducing water stains, such as kitchen

ZIXILAI conducted a series of low-temperature experiments in a self-made semiconductor refrigeration chamber, and the results showed that the superhydrophobic surface has good ability to delay icing and suppress frosting. Superhydrophobic surfaces have broad potential for basic research and industrial applications. A typical application is to use the self-cleaning function of superhydrophobic coatings to achieve

Due to the superhydrophobicity and self-cleaning properties exhibited by the “lotus leaf effect” of lotus leaves and water striders, people have launched in-depth research on superhydrophobic materials. The discovery of superhydrophobic materials has created favorable conditions for some underwater operations and the use of electronic products in humid environments. Common superhydrophobic materials on the market

A. In the following figure θ C is called contact angle, which is a measure of the degree of wetting. Definition: Contact angle refers to the angle between the tangent line of the gas-liquid interface at the intersection of gas, liquid, and solid, passing through the boundary between the liquid and the solid-liquid interface θ
