Anti-Fog Glass
by Alistair Phillips on December 7, 2005
A large percentage of driving accidents are caused by visibility problems and trying to drive with a windscreen that is fogged up can be lethal. Now a group of scientists at the Massachusetts Institute of Technology are saying that they may just have a solution for us.
Michael Rubner and his team have used nanotechnology to create a coating that can be applied to glass. This coating, which is smooth to the naked eye, actually consists of polymer chains and uses a positive to negative force actually bind to the glass.
Layer upon layer is created with the end result being a very porous coating. Water droplets fall into these pores and form a uniform sheet using a “wicking” effect. So water droplets are not created on the surface of the glass and as such cannot scatter light so you end up with a very transparent glass / lens.
