La ce foloseste vantablack?

Absoarbe un procent foarte mare din radiații, dar mie îmi folosește doar la muzică.

Applications
Being one of the darkest materials (for example MIT has developed in 2019 a material which reflects 10 times less light[16]), this substance has many potential applications, including preventing stray light from entering telescopes, and improving the performance of infrared cameras both on Earth and in space.[13]

Vantablack may also increase the absorption of heat in materials used in concentrated solar power technology, as well as military applications such as thermal camouflage. Its emissivity and scalability support a wide range of applications.

In addition to directly growing aligned carbon nanotubes, Vantablack is made into two sprayable paints with randomly-oriented nanotubes, Vantablack S-VIS and Vantablack S-IR with better infrared absorption than the former. These paints require a special license, a temperature of 100–280 °C, and vacuum post-processing.[17] Surrey NanoSystems also markets a line of non-nanotube sprayable paints known as Vantablack VBx that are even easier to apply.[18]
