The Blackest Material

QuantumCrypto writes "Researchers at Rensselaer Polytechnic Institute have created 'the world's first material that reflects virtually no light.' This anti-reflection technology is based on nanomaterial and could lead to the development of more efficient solar cells, brighter LEDs, and 'smarter' light sources. In theory, if a room were to be coated with this material, switching on the lights would only illuminate the items in the room and not the walls, giving a sense of floating free in infinite space."

  1. Possible uses for the military? by purpledinoz · · Score: 4, Interesting

    It says that it reflects virtually no light. I wonder if that includes the frequencies that are used for radar. If it doesn't reflect any radar signals, that could radically change military aircraft. Currently, military aircraft use shape as well as radar absorbing materials to achieve their stealthy-ness. Imagine if you can coat an F-16 with this stuff, and bam, you have a pretty cheap stealth fighter.

    The TFA is about a perfectly black coating that reflects nothing. This does not imply that it is transparent as you seem to be inferring.

    I hate to be a warmonger here, but this stuff could probably be used in military applications as well, probably for night ops and the like. A modern day ninja outfit with this stuff comes to mind


    Contrary to popular belief, the best color for urban night camoflage is not solid black. Depending on the environment, it's either charcoal grey (for general hard-to-see-ness), or irregularly-patterned greys (to break up the outline of your body).

  4. Claustrophobics rejoice by GiovanniZero · · Score: 4, Interesting
    Assuming this isn't just vaporware...

    This stuff could be really cool for use in MRIs or other tight spaces that claustrophobics normally have to go into. It would give those that are normally afraid to be in small spaces the sense that they were in a vastly infinite space. That's pretty cool IMO.

    I'd also like to have my home theater coated with this stuff, think about how large your house would feel! Even with low level ceilings.

    Indeed. This is because everything occurring in nature tends to reflect some light, even in the dark, when there isn't much to reflect. Solid black doesn't reflect enough, and subsequently actually stands out like a big empty void in a gray jumble of dimness.
