The American researchers forced water to jump aside from a surface as if a ball. The team of the professor Juli Crockett created a superwaterproof surface which cannot be wetted. Scientists argue that found a way which provides the maximum watertightness to a material for long time.
The superwater-proof surface developed by researchers from University of Brigam Young (BYU), can be applied to any product, beginning the smartphone and finishing boots. In the future with its help it is planned to protect cases of the ships and planes, the British newspaper Daily Mail writes.
It is impossible to receive a superwaterproof surface by means of only one teflon or wax. It is necessary to give to it a certain structure — professor Crockett from Brigam Young’s University explains, adding that it can achieve in the different ways.
In photos examples of the structured surfaces below are shown.
At hit on a surface of a drop of water start to jump on it as a ball. Artificially created structure forces drops to gather to spheres while water completely will not leave from a surface.
Engineers bounce water off superhydrophobic surfaces BYU mechanical engineering professors Julie Crockett and Dan Maynes study superhydrophobic surfaces, or surfaces that are extremely difficult to get wet. In layman’s terms, it’s the most extreme form of water proof. In their lab they’re analyzing how water beads up or bounces off the superhydrophobic surfaces they are creating by etching microscopic ridges or posts onto CD sized wafers. Engineers like Crockett and Maynes have spent decades studying superhydrophobic surfaces because of the plethora of real-life applications. And while some of this research has resulted in commercial products that keep shoes dry or prevent oil from building up on bolts, duo of BYU professors are uncovering characteristics aimed at large-scale solutions for society. Their recent study on the subject, published in academic journal Physics of Fluids, finds surfaces with a pattern of microscopic ridges or posts, combined with a hydrophobic coating, produces an even higher level of water resistance – depending on how the water hits the surface.

The new technology can allocate many surfaces, for example solar batteries, protection against water and ability to self-cleaning. Flowing-down drops of water will not leave traces. The scope of technology is rather wide: sanitary devices, medical devices, vehicles and many other things.
Researchers consider that their development also can be useful for obtaining more net and effective energy. Power plants generate energy at the expense of burning of coal or natural gas. Decrease in expenses on energy production is possible at the expense of use of the condensate which is forming from products of combustion. For this purpose condensers should have a superwaterproof surface.
Results of research were published in the Physics of Fluids magazine («Physics of liquids»).
