What are the hopeful uses for making ever more absorbing black materials?

I'll lay down a guess that having a better understanding of EM spectrum absorption -- in any wavelength -- likely has all kinds of applications. Better stealth technology, improved shielding for EM emitters, and possibly improved reflectors as well.

reducing stray photons in instruments, you only want those that go through your lens array, not those bouncing off the housing.

It would be interesting to test performance of a single fibre optic thread pulled through and coated with this to see the performance output.

Serious question: How do these materials both perform against radar? Will we be seeing them as stealth paints on planes or satellites?

Follow-up serious question: if I paint my car with this stuff, can a policeman tag me with his radar gun? If I wear clothes impregnated with it, would it confuse a "smart" surveillance camera? I'm also thinking if I used it as war paint, a facial recognition cam would probably be awfully confused by what appears to be a hole in my face.

I love this line of thinking!!

Also, if i were to dimple an an entire plane’s body like a golf ball, and paint it with this... how stealthy would that be?
