Super-Hydrophobic Metal

Researchers at the University of Rochester’s Institute of Optics in New York have developed a new type of hydrophobic metal that is so highly water repellent, it causes droplets to bounce off the surface.

Unlike other hydrophobic surfaces that employ chemical coatings, such as Teflon, this new hydrophobic surface is created by etching microscopic parallel grooves into the metal itself using lasers.

Potential applications for this material include rustproofing architecture or transportation such as automotive bodies or airplane wings (to resist icing).

See our Materials Focus 2016-17 rationale Super-Smart for further inspiration on adaptive and smart materials.
