Problems solved by technology

Based on this, researchers have prepared various biomimetic superhydrophobic coatings, but most superhydrophobic coatings are difficult to be applied in practice. There are two main reasons for this: first, the preparation cost of superhydrophobic coatings is high 1. The process is complicated; the second is that most superhydrophobic coatings only pay attention to their superhydrophobicity, while ignoring other properties necessary for engineering applications

Description

technical field [0001] The invention belongs to the field of glazes, and in particular relates to a method for preparing a hydrophobic and antifouling bottom glaze slurry. Background technique [0002] The unique properties of superhydrophobic surfaces make them have broad application prospects in the fields of self-cleaning, anti-corrosion, drag reduction, etc., and have always been an important topic of research for researchers. In the research of superhydrophobic performance, it is found that there are two main factors affecting the hydrophobic performance of the surface: one is the chemical properties of the surface material, and the other is the microstructure of the surface. Based on this, researchers have prepared various biomimetic superhydrophobic coatings, but most superhydrophobic coatings are difficult to be applied in practice. There are two main reasons for this: first, the preparation cost of superhydrophobic coatings is high 1. The process is complicated; th...
