Background

The antifogging material has important application in the fields of buildings, interior decoration, motor vehicles, personal articles (glasses, helmets, protective glasses and the like), aerospace, camera monitoring and the like. For example, glasses and swimming goggles are fogged, and can block the sight of people, thereby causing potential safety hazards. Automobile windshield rides the helmet and hazes, has the hidden danger that arouses the traffic accident, and the performance of instrument then can be influenced in optical instrument camera lens, display screen surface fogging, and the family adorns silver mirror fogging, can bring the life inconvenience.

For the traditional electrothermal antifogging structure, the antifogging performance is mainly realized by the fact that the surface temperature of a base material is similar to the environment through electric heating, so that the electrothermal antifogging material cannot be directly used on glasses, glass and the like, and external energy needs to be consumed. Therefore, the development of the electrothermal antifogging material is limited by energy consumption, potential electric hazards and non-universal applicability.

For a super-hydrophilic anti-fog structure, the anti-fog performance is mainly realized by depending on the property of a super-hydrophilic material, and when a super-hydrophilic coating is in a water vapor environment, water drops on the surface of the coating can be rapidly spread to form a thin water film, so that the anti-fog function is realized. However, such coatings often require light in practical applications, and also have problems of low strength, poor durability, and the like.

In summary, the current antifogging materials still have the defects of potential safety hazard and inconvenient use, or the defects of poor mechanical property, low strength, poor water resistance, complicated preparation process and the like, and the application of the antifogging coating is greatly limited by the defects. Therefore, it is necessary to provide an anti-fog and anti-frost structure with high strength, anti-fog and water resistance, which has simple preparation method, no potential safety hazard and wide applicability.
