Water Bounces Off New Super-Hydrophobic Metal Pattern
Scientists at the University of Rochester have developed a pattern that makes metal so hydrophobic that water bounces off it without any coating.By Sebastian Martinez | January 21, 2015
Water likes metal: It sticks to the surface and isn't easy to shake off because of how the two interact on a molecular level.
Now, scientists at the University of Rochester have found a way to make metals have the opposite effect. Water doesn't just slide off it; it bounces off. (Video via University of Rochester)
As detailed in the Journal of Applied Physics, scientists achieved this by using extremely powerful lasers, fired in extremely short bursts, to create the pattern, mimicking hydrophobic surfaces in nature.
