'The blackest substance in the world' that transcends black is born, and the unevenness of the coated material becomes indistinguishable visually.

'Black' is

a color that is difficult to handle and should not be used in design because it overwhelms other colors. Among such black colors, 'the blackest substance in the world ' was exhibited at the Farnborough International Airshow held at Farnborough Airport in the south of England, and has attracted a lot of attention.

The Real New Black: Scientists Have Created A Material That Is Blacker Than Black

The 'blackest substance in the world' is named 'Vantablack', which was successfully developed by Surrey NanoSystems , a global nanotechnology developer in the United Kingdom.

Vantablack is said to be the blackest in the world because of its overwhelming visible light absorption rate. Normally, the visible light absorption rate of black is about 95 to 98%, but the absorption rate of Vantablack is 99.965%, which absorbs most of the light.

In the case of normal black, the presence or absence of unevenness can be confirmed by the reflection of light, so it is possible to visually confirm the shape of the substance.

However, Vantablack absorbs most of the light, so the coated one is so black that the human eye can't tell what it looks like, and it looks like it's just a black hole. is. The image below shows a part of the aluminum foil coated with Vantablack and crumpled, but it is completely unclear what kind of unevenness the aluminum foil in the black part has.

Ben Jensen, CTO of Surrey Nano Systems, said, 'When you look at the crumpled part, it seems strange that there is a black hole in your eyes and nothing is there. Let's do it. ' Jensen didn't disclose the detailed cost of Vantablack, but when asked about the feasibility of dressing with Vantablack, he said, 'It's going to be very expensive.' All the features of the dress will be lost and it will just be black. '

If a dress really coated with Vantablack appeared, all the normally visible features of the dress, such as the laces and seams, would disappear and the dress wearer's head and limbs would emerge from the black holes. It will be as if it were.

Vantablack applies Surrey Nano Systems' patented low-temperature carbon nanotube manufacturing technology. Carbon nanotubes are extremely small substances that are 1 / 10,000th the size of human hair. Vantablack boasts high thermal conductivity, transfers heat 7.5 times more efficiently than copper, and has 10 times higher tensile strength than steel. Due to these characteristics, it is possible to prevent the separation of gas particles at a level that is virtually undetectable, and it is said that it can also be useful for removing dirt from the image sensor.

Vantablack is also suitable for coating internal components such as MEMS , which makes it possible to absorb shocks and withstand long-term vibrations.

In addition, Vantablack is said to be able to evolve optical systems such as astronomical cameras, telescopes, and infrared scanning systems to the 'next level'.
