British tech company Surrey Nanosystems says its developed the worlds blackest material: made of carbon nanotubes, it can absorb 99.96 percent of light that hits it. Super-black carbon nanotube coatings are used in telescopes and other instruments that need to operate without any kind of noise from reflected light. Back in 2010, NASA announced that it was assessing whether its own carbon nanotubes should be used to coat the Ocean Radiometer for Carbon Assessment, which measured ocean color and had to be covered in black paint to prevent contaminating the results. The explanatory video below introduces the concepts that underlie it and Surrey Nanosystems technology.
