Super-Hydrophobic Coating Using Tungsten Trioxide

The super-hydrophobic coating using tungsten trioxide not only has UV resistance (UV or UV), but also has excellent self-cleaning ability, good mechanical properties and stable performance. One of the biggest defects of super-hydrophobic surfaces is poor mechanical properties.

Super-hydrophobic coating using tungsten trioxide is known due to their unique waterproof properties and is widely used in research fields such as self-cleaning. It also knows what the “Lotus Effect” – water droplets can roll freely on a hydrophobic surface and carry away all the dust on it, ultimately keeping the surface clean. Tungsten trioxide has this special wetting property. So what is tungsten trioxide?

Tungsten trioxide is one of the most promising photochromic materials in the world, and it has great application value in many fields such as protection, decoration, data storage and so on. What is photochromism? Photochromism is a phenomenon in which a material can undergo a reversible color change after being excited by certain specific light sources. Tungsten trioxide is also an indirect semiconductor material with a wide bandgap value in the 2.6-3.3 eV range.

For super-hydrophobic surfaces, proper roughness and low free energy are critical. To date, there are many ways to effectively increase the roughness of a solid surface, and the use of hydrophobic particles is one of the most common methods. These particles are generally capable of forming a coating on a solid surface by certain means to alter the properties of the solid surface. In this way, various functional hydrophobic coatings can be achieved by simply changing the basic properties of the particles.

However, the rough structure of the solid surface is easily destroyed. One of the biggest defects of the super-hydrophobic coating surface is their poor mechanical properties, which greatly limits their application in real life. Therefore, it is an urgent need to improve the mechanical properties of the super-hydrophobic material surface.

In recent years, in order to solve the problem of poor mechanical properties of super-hydrophobic materials, a lot of research has been done. However, most of the super-hydrophobicity of the material surface can only be maintained under mild experimental conditions. Therefore, it is still a challenge for scientists to successfully obtain a super-hydrophobic material surface that is stable and has excellent mechanical properties. In addition, in practical outdoor use, UV resistance is also important for a super-hydrophobic coating surface. Therefore, it is of great practical significance to be able to prepare a super-hydrophobic coating with good mechanical properties and UV resistance.
