The structure is on approximately the same scale as the wavelength of visible light. I think that's in common with other recent ultra-black materials, it's either that there's just a huge amount of surface area or some sort of quantum-mechanics effect.
- rejuvenile 14y agoAerogels can have a surface area of ~2,500 m2 g-1, which is incredibly high. I wonder if this material, being made of carbon and likely having a similarly high surface area, would make a good capacitor.
