Shape Memory Plastics

from the polymerdirt-lives! dept

It's been a while since we've posted any "polymerdirt" articles, and our resident soon-to-be polymer chemist went and changed careers on us. But, for old times sake, here's an article about shape memory plastics, which are polymer structures that can be bent and twisted, but at certain temperatures will automatically return to a certain shape. The article talks about how useful these can be in medical devices, and other things like robots. Of course, I'm sure our former polymer chemist expert will enlighten us on where the article went wrong.

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.

While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

    still into polymers...

    Ok. I'm still a polymer chemist, dude. check your facts.... :)

    So these polymers are kinda cool. What they don't tell you that it's not like you can even lift a paperclip with these plastics. Developing the super-cool shape-memory plastics of the future is still a ways off. Also, they don't seem to mention that shape memory plastics have been around (and commercially important) for decades. What about heat-shrink insulation? That's technically a shape-memory polymer.... Are you going to build robots with it? Sure, if you need to splice together some wiring.... Artificial muscles aren't quite there yet.

      Composite Technology Development (CTD) has developed Elastic Memory Composites (EMC) materials. These are fiber reinforced composites using a CTD formulated elastic memory matrix material. Actuators have been built that have been able to lift 30 times their weight against gravity. It is cool stuff! Got any ideas for us?

      Re: still into polymers...

      I am a sixth form student at The misbourne school in the uk i believ it is grade 11 in the usa. i have to do a power point presentation on a material and i chose memory platics. If you know can you tell me where i can get more information about these "memory plastics"
      Thanks
