Self-cleaning Glass: The Future Is Here

How Does Self-cleaning Glass Work?

As you have probably guessed, the glass is covered with a special coating.  This ultra thin coating consists of titanium dioxide, which is usually found in paint, toothpaste, and numerous other bright white things. Titanium dioxide is not really transparent but the coating added to these windows is so thin that it only reduces the amount of light passing through them by 5%.  

This compound is used because it is photocatalytic, meaning it is light-activated.  Basically, as ultraviolet (UV) light from the sun (even on cloudy days) hits titanium dioxide when there is moisture in the atmosphere, a chemical reaction takes place which produces hydroxyl radicals.  These radicals are great at breaking down organic matter.

Additionally, unlike glass, it is hydrophilic, meaning that water does not form droplets on its surface. Instead, when water hits the surface of self-cleaning glass, it spreads out in an even layer and drops down neatly without any streaks.

So, how do these two properties of Titanium dioxide keep windows clean? Well, as water droplets or moisture hits the surface of the glass, it spreads out to create a “liquid cleaning-sheet” which washes away the broken-down organic matter. As a result, you have clean windows without any need to wipe away moisture or dirt!
