Webb1 nov. 2024 · One of the mechanistic concepts in CuAAC self-healing is the optimization of molecular diffusion via molecular design. The self-healing material can be design as multivalence, star-shaped or graft architectures [5]. Further, the use of multivalent azide/alkyne provides fast cross-linking in self-healing materials [11].
