By coating, not subject to icing. It can be used to create aircraft

Now in order to prevent icing of power transmission lines, turbines and aircraft hulls are used special chemicals, which reduce the freezing point of water, do not allow ice to form and so on. However such mixtures are not always effective and expensive and scientists have developed a special type of coating, which, using the energy of sunlight, does not form ice. In this further process it is no "chemistry" is not necessary. The coating works "in itself."

For the development of responsible experts from the Massachusetts Institute of Technology (MIT). And it covers the device itself is quite simple. It is based on a three-layer material which has the ability to collect solar energy and convert it into heat. Moreover, the resulting energy is distributed over the entire surface of the coating, not only heated at the point where a ray of sunlight hit. With this new material works at night, "eating" from artificial light sources. Led by a team of scientists who developed the coating, MIT professor of mechanical engineering creep Varanasi. He also explained the principle of the device of his invention in an interview with Science Advances,

"The top layer absorbs 95% of the solar light, converting it into heat. Next is a layer of aluminum thickness of 400 micrometers, which is heated by the absorbing layer. Well, the lowest layer penoizoliruyuschy. It is needed in order to reduce heat loss and keep it on the surface. That is exactly where we need. "

All materials have been selected in such a way that the "thermal response" has been rapid, and the heating was faster freezing. In this case, all three layers are made of the most accessible materials in order not to increase the cost of production.

Freeze drops of water on the new material

Now scientists want to test the material outside the laboratory, covering them a few roofs. After that experts will continue to work to improve the material in order to increase its strength and durability.
