Scientists make metal so super-hydrophobic, so waterproof, that droplets simply bounce off. Watch the video…
Scientists at the University of Rochester have used lasers to transform metals into extremely water super-hydrophobic, or repellent, materials without the need for temporary coatings.
Super-hydrophobic materials are desirable for a number of applications such as rust prevention, anti-icing, or even in sanitation uses.
In a paper published in Journal of Applied Physics, Chunlei Guo and his colleague at the University’s Institute of Optics, Anatoliy Vorobyev, explains, most current hydrophobic materials rely on chemical coatings. Describe a powerful and precise laser-patterning technique that creates an intricate pattern of micro- and nanoscale structures to give the metals their new properties.
