The new darkest manmade material, with its 0.045 percent reflectance (center), is noticeably darker than the 1.4 percent NIST reflectance standard (left) and a piece of glassy carbon (right).
Researchers at Rensselaer Polytechnic Institute and Rice University have created the darkest material ever made by man. The material, a thin coating comprised of low-density arrays of loosely vertically-aligned carbon nanotubes, absorbs more than 99.9 percent of light and one day could be used to boost the effectiveness and efficiency of solar energy conversion, infrared sensors, and other devices. The researchers who developed the material have applied for a Guinness World Record for their efforts.
