Optically healable/photo-healable polymers are a type of stimuli-responsive, self-healing polymer that harness the external visible or ultraviolet (UV) light to activate the self-healing reaction around the fracture interface.
There are several optically healable mechanisms based on the structure/composition of the polymers. The self-healing can be achieved through reversible dynamic covalent bonds, metal-ligand coordination, photoisomerization, and non-covalent bonds.
For example, when a metallosupramolecular polymer is exposed to UV light, the metal-ligand motifs are electronically excited and the absorbed energy is converted into heat. This causes temporary disengagement of ...
