World's First Single-Atom-Thick Fabric

Posted by CowboyNeal on from the barely-there dept.

neutron_p writes "Researchers at The University of Manchester have made the world's first single-atom-thick fabric, which reveals the existence of a new class of materials and may lead to computers made from a single molecule. They call it graphene, because it's 'webbed' by extraction of individual planes of carbon atoms from graphite crystal. The nanofabric belongs to the family of fullerene molecules, which were discovered during the last two decades, but is the first two-dimensional fullerene."

    Seriously, does this mean the edge of the fabric is really sharp? Can it cut through stuff?

      I want to know, if you had a sheet of this stuff about 1cm by 1cm... could you see it? does light permeate it? refract off it in rainbows?

      Can you keep it stiff? Paper will cut you if you can keep it stiff enough to slide your finger along the edge with a little pressure, but silk cloth of the same thickness won't because it isn't stiff.

      If you can figure out a way to make it rigid, you'll have a nifty new razor blade.

      Fullerenes conduct electricity, so its refractive index is most likely negative and it would be opaque if it were thicker. But the skin depth is on the order of a micron so individual fullerene sheets are transparent.

      Nope. It's not rigid.

      But.. if you could add a layer on top of that layer, juxtaposed by the minimal amount (half of a ring, see this picture of graphite crystal structure), and then add another layer, and another..

      Then you could form a 'perfectly sharp' knife.

      I'm not sure how durable it'd be though, because the inter-layer bonds in graphite are rather weak.

  2. Would someone be allergic to it? by Dancin_Santa · · Score: 5, Interesting

    Something that small and fine could possibly become airborne and eventually irritate allergic responses.

    Not to mention that consumption of the material could lead to carcinogenic effects.

    Before we start throwing around phrases like "wonder material" and "the future is now", perhaps we should take a closer look at the health risks involved in making/using these practically invisible materials.

      Nah, it has to be micron-scale (1000x larger) for your lungs to recognize it as foreign, and eject it. Like it does with dust.

      Not that that's a good thing. People get asbestosis and silicosis for just this reason. Sharp particles that are beneath detection become embedded. And if they aren't broken down and stay sharp, they cut, cut, cut at the cellular level for the rest of your life.

      As for graphene becoming airborne, lodging in the lungs, and never breaking down, who knows?

  3. can you tear this? by the_2nd_coming · · Score: 4, Interesting

    I mean, the fabrics we know can be torn because the atoms are clumped into partitions that we shove together, but this fabric is one layer of chemically bonded carbon atoms. that is some tough stuff.

  4. Re:Didn't RTFA... by toddestan · · Score: 4, Interesting

    They say in the FA that the fabric is "highly flexible and strong". But they only have samples roughly 10 microns large at this point, and the article doesn't really give any indication how well this will scale up. What I really want to know is if this stuff is airtight, or even watertight. If it is, I wonder if it would have any use in creating an ultralight spaceship?

    As far as sitting inside a hull one atom thick...be my guest. But maybe one application would be creating insanely large solar sails that fold up extremely small. You could even carry lots of spares.
