Vantablack® is a super-black coating that holds the world record as the darkest man-made substance, it absorbs 99.96% of it’s light. Copyright Surrey NanoSystems.
► WHAT IS VANTABLACK? - Vantablack is not a black paint, pigment or fabric, but is instead a functionalised ‘forest’ of millions upon millions of incredibly small tubes made of carbon, or carbon nanotubes.
Each nanotube in the vantablack forest has a diameter of around 20 nanometres (that’s about 3,500 times smaller than the diameter of the average human hair), and are typically from around 14 microns to 50 microns long. A surface area of 1 cm2 would contain around 1,000 million nanotubes
► HOW DARK IS IT? - Vantablack has been recognized by Guinness World Records as the World’s Darkest Man-made Substance. It is the darkest material ever measured by the National Physical Laboratory in Teddington, UK, reflecting only 0.036% of the light that strikes it (measured at 700nm).
