"Vantablack is a brand name for a class of super-black coatings with total hemispherical reflectances (THR) below 1.5% in the visible spectrum. The coatings were invented by Ben Jensen, who first publicly unveiled them in July 2014, and commercialised by the scientific team from Surrey NanoSystems. The original Vantablack coating was grown from a chemical vapour deposition process (CVD) and is claimed to be the "world's darkest material", absorbing up to 98% of visible light perpendicular to the material at 0 nm."
