A new discovery made by scientists at the University of Toronto may revolutionize how we protect surfaces from ice. By supercooling a water droplet, they have developed a superhydrophobic ice-repellent surface that can last up to two years. This breakthrough could have major implications for the automotive, aviation, and construction industries, among others. The technique involves applying a mixture of surfactants, polymers, and nanoparticles to a surface, which makes it so that the water droplet supercools without freezing. This allows ice to form around the droplet without actually sticking to the surface, meaning that any buildup of ice can be easily removed.
