Vantablack

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 original Vantablack coating was grown from a chemical vapour deposition process (CVD) developed by Surrey NanoSystems in the United Kingdom and is one of the darkest coatings known, absorbing up to 99.965% of visible light (at 663 nm if the light is perpendicular to the material). The coatings are unique in that they are not only super-black but that they retain uniform light absorption from almost all viewing angles. Original CVD Vantablack is no longer manufactured for commercial applications as it has been superseded by Vantablack spray coatings that offer similar optical performance in key parts of the electromagnetic spectrum.

The name is a contraction of the acronym VANTA (vertically aligned nanotube arrays) and the color black.
