I know what you mean, Rob. It's a little hard to believe because we don't actually see the material coming back together. But still, if it does what it says, it's a pretty incredible invention with lots of potential.
If this polymer can be commercialized, I can see it acting as a protective skin on products. When a cut occurs on its surface, its self-healing properties could close up the opening after several hours to prevent further damage.
I just read about this polymer the other day. It is certainly very impressive, its healing ability might capture the attention of alot of material engineers which can bring alot of advancement in the field.
