Abstract

To provide a polymer with a UV-responsive self-healing function and its manufacturing method, where a solid dynamic crosslinked polymer with a UV-responsive self-healing function is capable of being repaired and reprocessed through a dynamic exchange reaction of disulfide induced under exposure to UV radiation at ambient temperature when damaged after curing.SOLUTION: A polymer with a UV-responsive self-healing function is capable of self-healing simply through UV exposure at ambient temperature. Therefore, it can be utilized in the recycling of thermosetting resins that are environmentally challenging to recycle in the plastic industry, and furthermore, serve as an alternative to address various environmental issues.SELECTED DRAWING: Figure 7
