Blacker than black, carbon nanotube coating formed from a record low reflectivity

The British company Surrey NanoSystems разработала JavaScript a coating based on carbon nanotubes with a reflection coefficient 0, 035% in the visible range. Presentation of a new material called Vantablack, will take place during an air show in Farnborough, July 19-20. So far, the researchers have demonstrated laboratory sample - sheet of aluminum foil is coated with coating on it. It absorbs 99, 96% of the incident light, because of what looks like a "black hole" with no reflections and shadows. In the photo section of the coated looks as if part of the frame just poured 100% black in an image editor, but in reality it looks exactly the same.





The new coating is primarily finds application in science - the creation of more sensitive optical devices. Vantablack will more effectively blackens the internal surfaces and parts of telescopes and cameras, allowing them to distinguish the very faint light from distant and faint stars. Materials to interested and the military, and in the future, if we can significantly reduce the cost of production, such coatings may appear in the consumer photo and video equipment. In Surrey NanoSystems not name exact price Vantablack, but admitted that it cost coverage is not cheap.

Properties of nanostructures of carbon effectively absorb virtually all the light been known for quite some time, but there was no method of applying such a coating at low temperature. The company's specialists have developed a low-temperature process of creating a coating with good adhesion - it is able to withstand handling and vibration during launch space rocket.
