Darker than Black: Vantablack - material of the future

Scientists have found a way to look into the heart of darkness. But if without jokes, something dark on the submitted images in the text is not a portal to another dimension, but at the same time and is not "photoshop". These are real physical objects, which were covered Vantablack - the darkest material known to science.

Darker than Black: Vantablack - material of the future

If you do not know, vantablack was created by British researchers back in 2014 and shortly afterwards was declared the darkest ever to create in material laboratories, capable of absorbing 99, 96 percent of the visible, ultraviolet and infrared light.

After a series of experiments with this material by Surrey Nanosystems, which, by the way, it and created, at the beginning of 2016 it was announced that in the world there is no spectrometer, which would have sufficient capacity to measure how much in fact this material can absorb light.

"Even if aimed at a high power laser beam has this material does not reflect virtually nothing. Prior to that we did not create enough "dark" material, so we simply do not have the right spectrometers that could as accurately show the level of reflection in the infrared range, "- say the creators Vantablack.

Material decided to make more practical, so the researchers created a "spray version of" vantablack, which, of course, turned out not so dark - based material spray absorbs "only" 99, 8 percent of the ultraviolet, visible and infrared light - but it capable of making three-dimensional objects is visually similar to the two-dimensional. Just look at the picture below and see for yourself:

So ​​how does this thing work?

At its core, the original material Vantablack is not a paint, dye or fabric. This special coating, established on the basis of millions of carbon nanotubes with a diameter of about 20 nanometers (approximately 3500 times smaller than the diameter of a human hair), and a length of 14 to 50 micron (1 nanometer equals 0, 001 microns). In other words, the surface area of ​​1 square centimeter may comprise about 1 billion of these tiny nanotubes. When light falls on the surface coated Vantablack, photons fill the gaps between the nanotubes and actually remain locked up, since simply bounce off the molecules of the material inside.

"The almost complete absence of the reflex ability allows you to create an almost perfect black surface" - the researchers say.

"To understand this effect, try to imagine myself walking through the forest of trees whose height is about 3 kilometers instead of the usual 10-20 meters. It is easy to imagine how a little light can reach you. "

Vantablack material is so dark that the human eye is almost unable to perceive it as our brain requires a reflected light, so that you can understand what is right in front of our eyes. The creators of the material say that people looking at the material, experience some degree of confusion, and some even say that when viewed on Vantablack see not a physical object, but rather some kind of bottomless black hole. Spray version material called Vantablack S-VIS and allows to use the material at a wide range of different surfaces. One of the potential areas of application - the creation of these stealth aircraft.

And here is how the three-dimensional mask sprayed her Vantablack. Our brains may seem that the mask just cut the same "photoshop".

And here's a picture of a spherical object, covered Vantablack S-VIS.

If you are already itching to get his hands such a thing myself, I hasten to disappoint. In the public domain, this material will not reach. Therefore, paint your car is canceled. However, if you are an employee of a major university or a museum, it is possible that you will be able to beg and sample.

Below you can watch a video that compares subjects 'ordinary' black objects coated Vantablack. The difference, they say, no comment.
