Peering through a steamy windscreen as the rain pours down could become a thing of the past thanks to a material developed by American scientists (Telegraph).
A team at the Massachusetts Institute of Technology have developed a coating which, when placed on the inside of the windscreen, will stop it steaming up.
It will also mean that drivers do not have to wait for the car’s rear window to clear before they can see what is behind them.
Until now, windscreen coatings have been unable to prevent the condensation building up because water droplets spread on impact with the glass and form a layer of frost in cold weather.
But on what is known as a ‘zwitter wettable’ coating, the water molecules are absorbed into the surface. According to the Telegraph, this means they effectively disappear before they can cause fogging or, in cold weather, freeze.
This is thanks to a technique known as hydrogen bonding, which will hold together the thin film of absorbent polymers on the windscreen.
