The world's blackest material can turn all objects into 'black holes'.

Vantablack, the darkest material in the Earth developed by British scientists, has a low capacity of 99.96% of visible light, ultraviolet light and infrared. Recently, new scientists have invented a new application of the world's darkest material, turning all objects into "black holes".

Scientists at Surrey NanoSystems have continued to improve more materials by increasing its black intensity. And in 2016 they claimed there was no spectrum in the world that could measure the amount of light absorbed by Vantablack, even high-energy lasers were swallowed up and nothing responded to people's eyes. see.

Recently, Surrey NanoSystems has launched a Vantablack S-VIS spray paint , which can be applied to Vantablack on any type of material surface. This special spray is not "black" with the original Vantablack material, but still has the ability to block up to 99.8% of visible light, ultraviolet and infrared light.

This paint is actually a special coating made of millions of carbon nanotubes, (each square centimeter of the surface is made up of billions of carbon nanotubes), each of which is about 20 nanometers long and 14 in diameter. - 50 microns (1 nanometer is equivalent to 0.001 micron).

When exposed to this surface, light will pass between carbon nanotubes, but will then be trapped inside and unable to respond.

We could not even recognize the face of the statue, because there was no light reflected.

In studying this type of Vantablack S-VIS spray, scientists hope to turn all objects into a "black hole" and be widely used in the future. For example, disguise, turn objects into invisible .
