  1. If you watched a video for how to super glue something together, it would take less time/effort than this. I understand it was an example, but self healing plastic that takes a day or heat… Ya, way better than glue!

  2. A material that was almost cut in half apparently fully reattaches it self by the assumption of self-healing properties in a controlled environment without using any other physical material…………cool 🙂

  3. Well that's not really "self-healing" being that human interaction was required to heat it for a day to mend back together. If it magically healed itself with NO interaction, only then would I call it "self-healing." Humans for the most part are "self-healing." At least for a majority of the bumps, bruises, and abrasions we endure…

  4. Hye Mr. Hanze Ying,
    I have few questions regarding your video.

    Which type of resin and healing agent do you use?
    Is the pre-polymer that cured in room temperature isolate in vacuum chamber?

  5. I think this explanation is only in surface level, just to expose to public what self healing polymer is all about. But to what I understand based on how these polymer cured, it is obviously a themoset and not a thermoplastics.Once the reagent was set as thermoset, and break apart (or cut) it cannot reattach by heat up just like thermoplastics does. However this video shows it was possible, and it does not need any applied pressure to "heal" the polymer back to the original dog bone shape. The only question is, how does the mechanical strength (tensile, tear maybe..) will be affected after the healing process, or other properties like thermal, physical, etc.
