Scientists at Laval University in Canada have successfully developed a new type of glass waterproof mist coating material, the coating will not have any effect on the optical properties of the glass. According to Prof. La Roche, the head of the research team, this new type of material is made of a polyvinyl alcohol-based water-absorbing material and has the property of preventing the formation of water mist on the surface that obscures glass and plastic. This ultra-thin coating material can remain on the glass surface for a long time, and can completely remove the water on the glass surface without forming any minute water droplets on the glass surface.
The researchers said that the difficulty of this technology is how to make the coating material and the glass surface can be combined together for a long time. They first applied a layer of special molecular material to the surface of the glass and used it as a base layer. The base layer showed a strong adhesiveness. Then, they apply the anti-fog material to it.
The researchers said that the existing anti-fog coating cannot withstand cleaning, so it needs frequent re-application, and the new coating technology only needs to be applied once. Related articles were published in the online edition of Applied Materials and Interface magazine.
