Re: Self-Healing Applications

I am writing a story now about this type of polymer being applied to battery design to help a battery self-heal cracks that appear over time during operation. I think this is a great application of this material: https://energy.stanford.edu/news/scientists-invent-self-healing-battery-electrode

Stay tuned for my story. It should post this week or next.

Good point, Elizabeth. There could be a whole range of applications for this product acorss many industries. It will be interesting to see how it pans out.

I've been wondering about that, too, Rob. Perhaps it could be adapted to prosthetics or other kinds of medical devices that people use so that if there ever is any kind of tear or malformation, it would fix itself without needing replacement. I wonder if any of our other readers can think of good medical applications for this?

Yes, it looks like a form of healing. I wonder if there's a medical application.

Another good application, Greg. This could be useful especially for products shipped long distances that could undergo damage.

As we've discussed before in DN, by definition a self-healing polymer is a single material that heals itself when damaged or broken. They are not adhesives that can be used to attach other materials together. We've covered self-healing and shape memory plastics before:

and see links at the end of that article.

That is an excellent question, John E. I don't know the answer--I think it is just a material that already has been attached. That's what I understand from the video and researchers. But if the two parts were made from the same material, I don't see why that couldn't work. It could be a really good application of the material.

Cold Welding?

Could this property be used to "weld" two parts together?  Or does it just work on two surfaces that were separated from eachother?

Right.  Perhaps these self-healing properties can also regenerate a water-tight seal on electronic packages should a cut occur (to prevent liquid ingress).
