MIT engineers develop “blackest black” material to date

28 october 2019

MIT engineers report today that they have cooked up a material that is 10 times blacker than anything that has previously been reported. The material is made from vertically aligned carbon nanotubes, or CNTs — microscopic filaments of carbon, like a fuzzy forest of tiny trees, that the team grew on a surface of chlorine-etched aluminum foil. The foil captures at least 99.995 percent of any incoming light, making it the blackest material on record. 
In connection with this, The MIT Center for Art, Science and Technology and the New York Stock Exchange presented an artwork entitled The Redemption of Vanity created by artist Diemut Strebe in collaboration with MIT scientist Brian Wardle and his laboratory. This artwork will be on display at the New York Stock Exchange until November 25, 2019. Within this project, a 16.78-carat natural yellow diamond worth $ 2 million provided by LJWest was coated using a new procedure of generating carbon nanotubes, the color of which was recently recognized as the blackest of the black palette, and this made the diamond seem to disappear into an invisible void.

The CNT material may be of practical use, for instance in optical blinders that reduce unwanted glare, to help space telescopes spot orbiting exoplanets.
“Our material is 10 times blacker than anything that’s ever been reported, but I think the blackest black is a constantly moving target. Someone will find a blacker material, and eventually we’ll understand all the underlying mechanisms, and will be able to properly engineer the ultimate black,” Brian Wardle, professor of aeronautics and astronautics at MIT, said. 
The researchers have published their findings in the journal ACS-Applied Materials and Interfaces.
