Liquids bounce off super-repellent surface

Brought to you by MconneX (http://www.engin.umich.edu/alumni)


A nanoscale coating that’s at least 95 percent air repels the broadest range of liquids of any material in its class, causing them to bounce off the treated surface, according to the University of Michigan engineering researchers who developed it.

In addition to super stain-resistant clothes, the coating could lead to breathable garments to protect soldiers and scientists from chemicals and advanced waterproof paints that dramatically reduce drag on ships.

In a demonstration, the surface repelled coffee, soy sauce and vegetable oil, as well as toxic hydrochloric and sulfuric acids that could burn skin.
