Washington, March 17 (ANI): Scientists have come out with the very first permanent anti-fog coating, which could eliminate, once and for all, the fog on eyeglasses, windshields, goggles, camera lenses, and on any transparent glass or plastic surface.
Universite Laval professor Gaetan Laroche and his colleagues used polyvinyl alcohol, a hydrophilic compound that allows water to spread uniformly.
The challenge was to firmly attach the compound to the glass or plastic surface.
To accomplish this, they applied four successive layers of molecules, which formed strong bonds with their adjoining layers, prior to adding the anti-fog compound over this base.
The result was a thin, transparent, multilayered coating that does not alter the optical properties of the surface on which it is overlaid. In addition, the chemical bonds that join the different layers ensure the hardness and durability of the entire coating.
"Existing anti-fog treatments don't have these properties and won't withstand washing, so the product application must be repeated regularly. Our coating, on the other hand, is permanent," said Professor Laroche.
The study was published in the online edition of Applied Materials and Interfaces. (ANI)
