As part of a new exhibition on the New York Stock Exchange, titled "The Redemption of Vanity," the blackest material in history has been presented, conceived by MIT engineers, who published the finding in the magazine ACS-Applied Materials and Interfaces.
Specifically, it captures more than 99,995 percent of any incoming light: in other words, it is a material 10 times blacker than anything previously developed.
The material is made of vertically aligned carbon nanotubes, or CNT, microscopic carbon filaments, such as a blurry forest of small trees, which the team grew on a surface of chlorine etched aluminum foil. This has succeeded in overcoming Vantablack. Brian Wardle, professor of aeronautics and astronautics at MIT:
There are optical and space science applications for very black materials, and of course, artists have been interested in black, dating back long before the Renaissance. Our material is 10 times blacker than anything that has been reported, but I think blacker black is a constantly moving target. Someone will find a blacker material, and eventually we will understand all the underlying mechanisms and we will be able to get the ultimate black.
In the exhibition, a natural yellow diamond of 16.78 carats has been presented, with an estimated value of 2 million dollars, than the equipment coated with the new CNT ultra black material. In this way, the gem, usually with bright facets, appears as a flat and black void.
