Engineers create the world’s darkest material

Never mind pink – ‘super black’ is the new, well, black.

Engineers at Surrey Nanosystems have created a new ‘super black’ coating. Originally developed for applications in space due to its low mass, ability to withstand a range of temperatures and an incredible absorption rate of 99.96% of incident radiation, it’s found a large number of other applications a bit closer to home. Imagine an optical sensor that can block out 99.96% of the unwanted light (including infra-red, UV and all the rest of the spectrum).

Unsurprisingly, the material is based on one of the two most useful materials currently being investigated: carbon nanotubes. (The other one’s graphene, by the way.)
