New amazing metal is so hydrophobic it makes water bounce like magic!
Scientists at the University of Rochester have created a metal that is
so extremely hydrophobic that the water bounces on it as if it were
repelled by a magic force field. Instead of using chemical coatings they
used lasers to etch a nanostructure on the metal itself. It will not wear off, like current less effective methods.
The applications can be revolutionary: From the construction of airplane
surfaces—which will avoid water freezing of the fuselage—to non-stick
pans to phones to computers to TVs to cars to whatever you can imagine
made of metal. They are also thinking of applying the technique to
create 100-percent efficient water recollection systems in
underdeveloped countries and the creation of latrines in areas where
water is not abundant enough to allow for effective cleaning.
But it gets even better: The lead scientist says that 'the structures
created by their laser on the metals are intrinsically part of the
material surface' so they will not disappear over time, like current
chemical coatings do.
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.
Here's Guo in a explanatory video along with the co-writer of the study,
Anatoliy Vorobyev, who is a professor at the University of Rochester's
Institute of Optics.
