Surfaces coated with Vantablack are highly suitable for emitting and absorbing blackbody radiation. Applications Īs one of the darkest materials, Vantablack has many potential applications, such as preventing stray light from entering telescopes, and improving the performance of infrared cameras both on Earth and in space. Vantablack is resistant to mechanical vibration and exhibits thermal stability. The outgassing and particle fallout levels of Vantablack are low compared to similar substances, which makes it more commercially viable. Darker materials are possible: in 2019, MIT engineers developed a CVD material which reflects a tenth of the amount of light that Vantablack reflects. NASA had previously developed a similar substance that was grown at 750 ☌ (1,380 ☏), which required materials to be more heat resistant than Vantablack. Vantablack absorbs up to 99.965% of visible light and can be created at 400 ☌ (752 ☏). ĬVD Vantablack was an improvement over similar substances developed at the time.

When light strikes Vantablack, instead of bouncing off, it becomes trapped and continually deflected amongst the tubes, absorbed, and eventually dissipated as heat. Properties Vantablack grown on metal foilĬVD Vantablack is composed of a forest of vertical carbon nanotubes 'grown' on a substrate using a modified chemical vapor deposition process. When applied to three-dimensional objects, Vantablack produces the appearance of a two-dimensional surface or void space.

Visual characteristics Īs Vantablack is composed of carbon nanotubes that absorb exceptionally high levels of visible light, it is widely considered one of the darkest pigments created. During the first showing of the colour, Chase, alluding to Vantablack, stated that 'its possibilities have been stunted by not being available to experiment with', and Singularity Black's release was important to create access. In response, Nanolab, a Waltham, Massachusetts-based carbon nanotube manufacturer, partnered with Boston artist Jason Chase to release a nanotube-based black paint called Singularity Black. Many artists voiced opposition to his monopoly over the substance. Controversy Ĭontroversy arose when Surrey Nanosystems granted Anish Kapoor exclusive rights to use Vantablack in artistic applications. In 2015, production was scaled up to meet demand in the aerospace and defense sectors. The first orders were delivered in July 2014. Several other firms also distribute vertically aligned nanotube arrays, including NanoLab, Santa Barbara Infrared and others. Īs of 2022, Vantablack coatings are very costly, and Surrey NanoSystems refuses to supply them to private individuals and provides samples only for applications they deem 'valid'. The Vantablack name is trademarked by Surrey NanoSystems Limited, and is referenced in three patents registered in the United States Patent and Trademark Office. History īen Jensen, founder and CTO of Surrey NanoSystems, invented the coatings, which were publicly unveiled in July 2014, and eventually commercialized by the scientific team from Surrey NanoSystems.Įarly development occurred at the National Physical Laboratory in the UK the term 'Vanta' was coined later in its development. 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 coatings are unique in that they are super-black and retain uniform light absorption from almost all viewing angles. 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 99.965% of visible light measured perpendicular to the material. The name is a combination of the acronym VANTA ( vertically aligned nanotube arrays) and the shade black. Vantablack is a class of super-black coatings with total hemispherical reflectances (THR) below 1% in the visible spectrum.
