Superhydrophobic Material Developed That Makes Water Bounce Like A Ball


 Engineers from Brigham Young University (BYU) are developing extremely waterproof surfaces that they believe could dramatically improve the efficiency of both power plants and solar energy systems. These surfaces, called superhydrophobic surfaces, are extremely difficult to wet since they cause water to aggregate and form beads that sit on the surface.
If you turn to nature you can see numerous examples of naturally occurring superhydrophobic surfaces such as duck feathers, butterfly wings and lotus leaves. These surfaces efficiently repel water, causing it to clump together and form little beads because it is more attracted to itself than the surface. These surfaces have inspired many engineers in the field of biomimetics, where scientists attempt to imitate elements of nature to solve problems. Read more.
