Researchers at the University of Rochester in Rochester, New York have created super-hydrophobic materials that repels water with extreme efficiency, using laser-cut micro- and nanoscale patterns, removing the need for temporary chemical coatings.
The material is so strongly water-repellent, the water actually gets bounced off. Then it lands on the surface again, gets bounced off again, and then it will just roll off from the surface.
The material, detailed in a paper published by The Journal of Applied Physics is more slippery than Teflon and is easily cleaned, as water bounced of its surface takes dust particles along with it.
