This new carbon nanotube material is the darkest thing on the planet
We know what darkness is: it's the absence of light, and something we each encounter when the sun goes down. Seeing darkness in broad daylight on the other hand, that's weird. It's also, astonishingly, a completely possible thing. Sitting on a piece of aluminum foil in Surrey NanoSystems' lab is something called Vantablack -- a low-temperature carbon nanotube material that absorbs 99.96% of all light that touches it. It's effectively the darkest material on the planet, and anything draped in becomes non-reflective, losing any and all surface detail. So, what's the point? This new ultra dark material uses a low-temperature process, which allows it to be applied to things like stealth vehicles or telescopes, allowing them to avoid detection or see farther, respectively. The firm says it's scaling up production for customers in the defense and space sectors. The company says it's already delivered its first orders, and says its working on an even darker version of Vantablack. Well, here's to a darker future. [Image credit: Surrey NanoSystems]
Scientists create darkest material ever
Researchers at a US laboratory claim to have created the darkest material ever; a carbon nanotube which is one atom thick and rolled into a cylinder. For an object to be completely black, it must absorb all the colors of light over every angle and wavelength while reflecting none back, and scientists at Rensselaer Polytechnic Institute in Troy, New York, may have just gotten one step closer. The team built an array of vertically aligned, low-density nanotubes -- rough on the surface to minimize reflections -- and then measured the optical properties. They discovered that the objects very good at absorbing light, while downright rotten at reflecting it, thus creating a new standard for "blackness." In practice, their nanotubes could form a super-black object, leading to the creation of more efficient solar panels or solar cells, or more importantly, a Kuro display that goes beyond absolute black. "They've made the blackest material known to science," Says Professor Sir John Pendry, though Shaft's representatives have called for a recount.
