The World's Blackest Material Just Got Even More Black
A group of British researchers made headlines for creating the blackest material known to science, in 2014. Called Vantablack, the material was so incredibly black, it only reflected 0.035 percent of all the light it absorbed, which means to our eyes, it was marginal invisible. Now another blackest material has been introduced and it is even blacker, with the inventors publicizing that no spectrometer in the world has capability to measure how much light it absorbs.
Up to now, all we know about this record-breaking material is what's in the video below, recorded by the Vantablack inventors at Surrey NanoSystems just seconds after they removed it from the reactor. Theteam explains "It's resulted in a coating so black that our spectrometers can't measure it. Even running a high power laser pointer across it barely reflects anything back to the viewer. We have never before made a material so 'black' that it can't be picked up on our spectrometers in the infrared."
Vantablack isn't a paint, dye, or even fabric, but is essentially an unusual coating made from millions of carbon nanotubes, each one measuring nearly 20 namometres - about 3,500 times minor than the diameter of a human hair - by 14 to 50 microns. To put that in viewpoint, 1 nanometre is equal to 0.001 microns.
Now, if you're still not aware of the blackest black material's blackness, here's Vantablack's record-breaking blackness matched with other shades of black:
