Carbon Nanotube Films Stronger Than Kevlar (acs.org) 39

ckwu writes: Carbon nanotubes are exceptionally strong and stretchy. But so far, films made out of them have come nowhere close to having the mechanical strength of individual nanotubes. Researchers now report a simple fabrication method to make carbon nanotube films that are five times as strong as those made before—and stronger than films made from Kevlar or carbon fiber. The films had an average tensile strength of 9.6 gigapascals. By comparison, Kevlar fibers and commercially used carbon fibers are around 3.7 and 7 GPa, respectively. The films are also four times as pliable as conventional carbon fibers, able to elongate 8% on average.

    Yah! We can start talking about space elevator again!

      I'm not so much interested in space elevator technology rather than flexible spacesuit technology and whether or not this material could be 3D printed.

    I'm not buying into obsolete technology. I'll wait and see what Graphene can do.

    Hi.

    Sheets and other shapes of carbon nanomolecules are known to have sharp edges that can tear up biological structures (cell membranes, for one). It is not clear if or how these carbon nanomolecules interact with biochemistry, or into what compounds the nanomolecules degrade (by nature or human effort) and what effect those breakdown products have on life chemistry.

    Where do we stand with testing the biological safety of these potentially magnificent compounds BEFORE we poison ourselves again by mistake, as we did with organometallics (dioxins, PCBs), synthetic estrogens (plastics), heavy metal pollution (pthalates, mercury), etc., etc.)?

    • heavy metal pollution (pthalates [sic], mercury)

      Phthalate refers to a group of chemical forms consisting of carbon, hydrogen, and oxygen. No metal.

    Is there anything they can't do?

    Other than make it to commercial production that is.

    Because when my wife lets the end of the roll slip back into the box, she will have to mail it back to the company to get it unraveled, rather than just waiting until I get home so I can do it.
