Scientists have created a plastic that simulates the eye of the moth

Singapore scientists are so inspired by the structure of the eyes of moths, which have developed by analogy with it a new high quality anti-glare plastic. They claim that this material will improve the quality of a variety of anti-glare screens and increase the efficiency of solar cells.

Moles can see perfectly in the dark, while the predators see it a lot worse. This is achieved by the fact that the eyes of moths cover Nanocones - repetitive bumps form. Incident light reflected from a wall of the cone and is incident on the opposite surface, which again is absorbed and so on. In connection with this moth eyes practically do not lose photons of light, the eyes of predators hardly get them.

Singapore engineers adapted to the natural development of plastic, the surface of which they are initially coated Nanocones and then laid upon them microstructure which additionally quenched reflected light. On the surface, the new plastics are tiny nanoscale roughness and smooth curves of a larger size. Borrowed from the moth structure has reduced the visible light reflection factor of five.

Testing the new plastic has shown that such polymeric material is much more efficient for all modern anti-reflective coatings. If the latter reflection is at least 1%, the new plastic albedo makes only 0.2%, and even at 45 ? this value does not exceed 0.7%.

The developers say that the new cover in the future will be used in the manufacture of displays, TVs, smart phones, navigation devices and even windows. In addition, developed by Singapore scientists structure will significantly improve the efficiency of thin-film organic solar cells.
