Abstract Self-healing polymers have attracted lots of attentions and have been extensively studied recently. Healing method includes external self-healing and intrinsic self-healing according to if healing agent is required in the healing process. External self-healing systems include dicyclopentadiene-based healing system, epoxy-based healing system, thiol-based healing system, glycidylmethacrylate-based healing system, maleimide-based healing system and so on. This review attempts to introduce the application and progress of external self-healing systems in epoxy polymer and discuss the future development direction.
