(Phys.org)—U.K.-based Surrey Nanosystems has announced that it has improved on the original Vertically Aligned Nanotube Array BLACK (Vantablack coating) which the company claimed to be the blackest material ever made. The original Vantablack was found to absorb 99.96 percent of visible (and ultraviolet and infrared) light—the new Vantablack is darker—so much so that it cannot be measured by a spectrometer.
