Vantablack is a material developed by Surrey NanoSystems in the United Kingdom and is one of the darkest substances known, absorbing up to 99.965% of visible light (at 663 nm if the light is perpendicular to the material).[4][5]

The name is a compound of the acronym VANTA (vertically aligned carbon nanotube arrays)[6] and the color black.

MIT engineers have created a blackest black coating from carbon nanotubes that is reportedly 10 times darker than any material created before, including Vantablack.

The coating, which is made from vertically aligned carbon nanotubes (CNT) grown on chlorine-etched aluminium foil, can absorb 99.995 percent of visible light.

“Our material is 10 times blacker than anything that’s ever been reported,” said Brian Wardle, professor of aeronautics and astronautics at MIT.

Vantablack, which was created by Surrey NanoSystems, absorbs up to 99.96 percent of visible light and wasn’t even the previous blackest black on record.

Anish Kapoor receives exclusive rights to blackest black in the world.

Indian-born British artist Anish Kapoor has acquired exclusive rights to the revolutionary Vantablack pigment, said to be the blackest shade of black ever created.

Kapoor – who designed the Orbit tower for the London Olympics – is currently the only person in the world who can paint using this colour, and has been doing so since 2014.

Although originally developed for military purposes and astronomy equipment, NanoSystems has confirmed to the Guardian that Kapoor alone can paint using Vantablack.
