The perennial de-icing of one's windshield on a freezing winter's morning is a common enough problem for those who live well outside The Tropics, but ice forming on glass in cryogenic laboratories and elsewhere is an all-round problem regardless of where your laboratory is. Now, researchers at Rice University have extended work for protecting radar domes from ice to find a way to coat glass with an anti-ice material. Last year the same team used overlapping nanoribbons and polyurethane paint to keep water liquid on military radar domes so that they perform optimally, the material could replace bulky and energy-hungry metal oxide frameworks. Now, the materials have been made more consistent and substantially radio transparent, which prevents them melting on the radar domes but also extends their use to glass windows for buildings and cars where getting a radio signal in and out is important for mobile phone communications, for instance.
