insulator coating
Since the concept of cleanliness was put forward in the 1990s, its research and commercialization have developed rapidly. At present, self cleaning coatings are not confined to the construction coatings industry. It also appears in many applications such as electrical and electronic equipment, automobiles and greenhouses, which are closely related to people's lives. Due to the advantages of environmental protection and cost saving, self-cleaning coatings are more and more popular in the market and will play an important role in the future.

According to the principle of self-cleaning, self cleaning coatings can be divided into super hydrophobic and super hydrophilic coatings, which achieve their own cleaning effect through the action of water. The difference is that superhydrophobic coatings remove pollutants by rolling on the bottom of the water, while superhydrophilic coatings achieve self-cleaning by forming water film on its surface and removing or isolating pollutants. Especially the latter has photocatalytic properties under light radiation, which can degrade organic matter and further play the role of disinfection and purification of the environment.

In the commercialized self-cleaning products, the most widely used form is self-cleaning energy which is closely related to people's daily life. Because the self-cleaning coating does not need maintenance, it is easy to use and it is conducive to environmental protection, which conforms to the development model of low-carbon economy. The development has the characteristics of water repellency, oil repellency, stable contamination resistance and convenient construction. It can be used for multi-functional self cleaning coatings on different materials. It is the future development direction of self cleaning coatings, but this process has a long way to go.
