http://www.belfasttelegraph.co.uk/ne...-30427632.htmlA British company has produced a "strange, alien" material so black that it absorbs all but 0.035 per cent of visual light, setting a new world record. To stare at the "super black" coating made of carbon nanotubes – each 10,000 times thinner than a human hair – is an odd experience. It is so dark that the human eye cannot understand what it is seeing. Shapes and contours are lost, leaving nothing but an apparent abyss.
Actual applications are more serious, enabling astronomical cameras, telescopes and infrared scanning systems to function more effectively. Then there are the military uses that the material's maker, Surrey NanoSystems, is not allowed to discuss.
The nanotube material, named Vantablack, has been grown on sheets of aluminium foil by the Newhaven-based company. While the sheets may be crumpled into miniature hills and valleys, this landscape disappears on areas covered by it.
"You expect to see the hills and all you can see … it's like black, like a hole, like there's nothing there. It just looks so strange," said Ben Jensen, the firm's chief technical officer.
It also has "virtually undetectable levels of outgassing and particle fallout", which can contaminate the most sensitive imaging systems. The material conducts heat seven and a half times more effectively than copper and has 10 times the tensile strength of steel.
