Vantablack is a class of super-black coatings with totalhemispherical reflectances below 1%.
The name is a portmanteau of the acronym VANTA (vertically aligned nanotube arrays) and black.

The original Vantablack coating was grown using a chemical vapour deposition process
and is claimed to be "the world's darkest material."
Absorbing up to 99.965% of visible light measured perpendicular to the material.

The coatings are unique in that they are super-black and retain uniform light absorption from
almost all viewing angles.
Original Vantablack is no longer manufactured for commercial applications.
