Now this is pretty interesting. If nanotechnology news gives you the warm fuzzies then you'll be pleased to learn that some chemists at the University of Zurich have created a new fabric that can't ever get wet. Ever. I mean, it was in water for two months and it's still not wet! This material is made from polyester which were covered with 40nm-wide silicone nanofilaments. Since these filaments are so tiny and so spiky, they make it so water actually sits above the material in a sort of pocket. This is a permanent state. The material won't ever be made wet. So what are the potential applications of this technology? Well, it reduces drag in water by up to 20%, for one. It can also serve as a self-cleaning cloth. Regardless of how it ends up being used, this is still pretty cool and presents numerous opportunities.
