What’s the best way to keep our screens clean? The first, and obvious answer, is to keep our hands themselves free of grime. But there may be another option: self-cleaning coatings created by materials scientists.
Recently, Anish Tuteja, a materials researcher at the University of Michigan, developed a clear, smooth coating that repels all liquids and can be applied to any surface. (The research was published in the journal ACS Applied Materials & Interfaces.) There are other repellent coatings, of course, but their abilities are limited. Take, for instance, a Teflon pan. “If you put a drop of water on it, it beads up, but if you put cooking oil, it’ll spread,” says Tuteja. “That’s what happens on most surfaces.” The material his team…
