Vantablack Darkest Material in the World Then they outdid themselves and made an even darker version. But in 2019, Vantablack was upended by a new element that became the blackest and darkest material in the world. Vantablack was made by a British company called Surrey NanoSystems, and it originally absorbed all but 0.035% of visual light when it came out in 2014. The company then made a new version of Vantablack that can be sprayed directly onto other objects. This version was so black that there wasn’t an optical spectrometer available anywhere in the world with the sensitivity to test it. The matter even absorbed light from a laser. Vantablack is made of millions of carbon nanotubes that are so tiny that each nanotube has a diameter of approximately 20 nanometers. That is 3,500 times tinier than the diameter of a human hair. When light hits the surface of the Vantablack, it enters the space in the millions of nanotubes. As light moves in the nanotube structure, it gets absorbed and can’t be reflected. This results in a black surface that gets as close as we know to what a black hole might look like as it reflects almost no light. It’s believed that one square centimeter of the surface contains one billion nanotubes, according to Surrey NanoSystems. The appearance of Vantablack creates dramatic effects since there is nearly no reflection from light. When it is put on a three-dimensional object, the object seems to be two-dimensional. Since Vantablack covers another surface, it’s almost impossible to see what the surface looks like. https://thegeekz.net/plastic-eating-bacterium-scientists-accidentally-made-it-stronger/ Any folds or wrinkles on a surface seem flat or as if nothing is there. The human eye is incapable to detect any surface changes without the reflection of light. Vantablack is created through a process in a chemical vapor deposition chamber that uses lamps to raise the temperature of the surface to 430º Celsius. According to Surrey NanoSystems, this provides a carbon “nanotube forest to grow,” and the name originates from the term Vertically Aligned Nanotube Arrays. Read the full article
