Futuristic 'Smart' Yarns from Carbon Nanotubes 216

Posted by Hemos
from the the-warmest-sweaters-ever dept.
neutron_p writes "Scientists at The UTD NanoTech Institute achieved a major technological breakthrough by spinning multi-walled carbon nanotube yarns that are strong, tough and extremely flexible, and are both electrically and thermally conducting. Among other things, the futuristic yarns could result in 'smart' clothing that stores electricity, provides ballistic protection and adjusts temperature and porosity to provide greater comfort. The breakthrough, made possible by, in effect, downsizing ancient technology used for wool and cotton spinning to the nanoscale, resulted from an unusual collaboration involving nanotechnologists and experts in wool spinning."

      Yes, and if it saves your life from bullets then you have to look forwards to a slow and painful death from all the numerous detrimental and very dangerous effects from exposure to carbon nanotubes.

      This is not safe stuff to just be casting around ideas of using in clothing. It's as irresponsible as the asbestos-impregnated children's clothing from the 1930s and 1940s.

    Am I the only one who thought of Fountains of Paradise by Arthur C. Clarke when reading this?

    For those that don't know, Foutains of Paradise [amazon.com] is where ACC first coined the idea of building an elevator into space which he later used in 3001: A Final Odyssey [amazon.com] (The 3rd sequal to 2001: A Space Odyssey). To build the elevator a super-strength carbon string was bundled into three bundles and then attached to a giant mass in space to keep the tethers taught. At least if memory serves me correctly that's how it was done. If you're an ACC fan and haven't read Fountains of Paradise, I recommend it.

    • This may have been the first time that Clarke wrote about a space elevator, but the concept was not original with him.

      Tsiolkovsky first proposed it in 1895.

    That's just in time (or just a bit too late?) to save many a developed country's ass - if I'm not mistaken in 2005 WTO members must abolish textile quotas and Chinese and Indian manufacturers are poised to make a killing.

    Products based on this technology will command premium prices (and have great features - I might finally become interested in shopping!).

    • About time they abolished those quotas. Given the dominance of imported textiles in the US already, it won't have that big an impact. If the remaining domestic producers want to stay viable, they can always shift to more boutique-style production touting the domestic nature of the product, and they'll still find buyers. Of course, it's easier to just bitch about foreign producers...

    I would not get my hopes up for getting a carbon nanotube sweater for Christmas this year or next year or the year after that... In the foreseeable future these nanotube yarns would be used to replace metal wires in applications where increased flexibility and pliability are required they could also be used for such things as capacitors or batteries. The authors of the article (Mei Zhang, Ken R. Atkinson and Ray H. Baughman, Science, 306, 5700, p1358-1361, 19 November 2004) state that the small yarn diameters (about 20 micrometers for the four ply yarn), could eliminate the uncomfortable rigidity sometimes found for metal wire-containing conducting textiles that provide radio or microwave absorption, electrostatic discharge protection, textile heating, or wiring for electronic devices. Although a bulletproof, electrically conductive vest that could withstand temperature extremes from +450C to -196C does sound quite appealing.

    Now, as can be demonstrated by many of my previous posts, I'm all for pure and applied science. However, lately, I've been thinking quite a lot on the question "what good is technology?". Yes, building a space elevator would be cool. Yes, having light bulletproof vests would be cool. But how does this science help mankind? Does it improve agriculture? Does it help provide things people need? Does it help the environment? Does it help people get along better?

    I know these are questions that don't have easy answers always, and I know that if people thought about these things in a literal sense then we probably would not have a lot of the technology we currently have.

    My question is more of this: what research is being done into pure sciences and technology that does work for agriculture, health, the environment, and those types of things directly. Some technology simply supports those things indirectly by providing jobs, new materials, etc.

    What is lacking in a lot of science, though, and much of life in general, is a lack of focus. Even in the pure sciences, what's the goal of a particular project? Sometimes it's "to see how things work". Sometimes it's "we would like a better way to do X". There is no overarching goal for a lot of modern technology though - mostly it's just "we want a profit!" (Reminds me of the line from Star Trek: First Contact where Zefram Cochrane says he wasn't in it for science but for profit!)

    I am by most measures a successful person, but I've had to ask myself: what good is it? Not from a depressed standpoint, but a "shouldn't I be doing more?" standpoint. Carbon nanotubes are great, but what do they really give us? The list goes on - what do Linux desktops give us? MP3 players (without DRM, of course!)? Wi-Fi? These are all neat things - but do we have a purpose behind our technical passions?

      Comparing Carbon nanotubes to MP3 players is like comparing the transistor to a Radio Flyer wagon.

      CNTs are like lasers. When the laser was invented in 1955 or so (someone correct me), it was billed as a "solution looking for a problem." No one knew what the hell to do with it. Naturally, it being the Cold War, most research money was pumped into Star Wars-style blasters...but now look at all the work done with lasers. Surgery, trace gas detection for pollution controls, CD players, DVD players, spectroscopy for materials science, the list goes on. The point is that CNT research is very early. Hell, nanotubes weren't known to exist until 1990 or so. This is one breakthrough out of about a billion or so possible with Carbon Nanotubes. Don't judge the technology based on the premise of "fancy clothing." Hell, the point of the link isn't the clothing part; it's the fact that a new fabrication method was invented that would improve production (and thus, deployment) of nanotubes by orders of magnitude. It's like finding a new way to make lasers on a broad scale instead of slowly making them by hand like in 1960. What you do with the plethora of nanotubes or lasers or what have you is up to you.

    This may be a really stupid question. Related to a recent study concerning the replacements for asbestos. Back in the 80:ies when it was discovered that asbestos would cause lung-cancer or worse after repeated exposion to it, they replaced asbestos rather swiftly with materials like cheramic fibres. Now, recently they discovered that replacements like heat-resistant cheramics could also cause lung-cancer this. Perhaps just as dangerous as asbestos. The reason found, was because of the micro-fragments (dust) which would gather in the lungs and it's air-sacks (alveoli) and make them to swell abnormally and then risk causing cancer.
    Even building insolation materials have also been questioned.
    Now to my concern regarding carbon fibre.. has there been any studies on carbon tubes's affects on the human body? Carbon-fibre is an artificial material such as many insolations questioned. That is why I ask.

    Somehow I have a feeling the ultrafine fiber fragments shed by these yarns or fabrics made from them with age and wear won't be so happy biologically.

    Generally small particles or fillaments of any material smaller than a certain size are bad for you if inhaled (i.e. Pneumoconiosis), regardless of their composition.

    Additionally, if fiber fragments are short and fine enough, you essentially have little needle-like objects that can do a lot of damage directly at the cellular level.

    So, not that I'm being pessimistic or anything, but in the long term I don't think it'll remain an everyday item. It might hit the open market for a while, but a few decades of cancer studies, toxicoligical studies and lawsuits would likely bring an end to that.

    While my guesses are just that, there are a few discouraging signs [cwru.edu] in research to date. Watch this area; we'll see whether further results warrant concern or not.

    To be clear, I think this technology should certainly be pursued, but we need to be guarded in our optimisim regarding its widespread applicability.

  • Since the CNT fabric is conductive -- imagine if you could have a jersey for running or cycling that had an embedded heartrate monitor. No more stupid straps digging into your chest!

    between the textile industry and computing industry... In the late 60s, before bipolar transistor memory or MOS transistor memories were commonplace and practical, companies like Digital and IBM employed several textile company weaving-experts on the efficient weaving of core memory "ropes" and "cloths." Basically, the problems encountered in the fabrication of core memory on a large, complex scale had been solved, or at least examined, centuries before. see Rope memory [ed-thelen.org] and Apollo Guidance Computer rope memory [ed-thelen.org]. And of course, who could forget the original programmed computer, the Jacquard's punch-card loom? [acusd.edu]
