Epoxy resins are widely used in our life due to their excellent thermal and mechanical properties, dimensional stability, and processability, but they are inevitably impacted by chemical/physical events, which leads to micro-cracks during use. Self-healable epoxy resins can repair the micro-cracks, greatly extending the life and safety of the resin. This chapter reviews the methods of achieving self-healable epoxy resins, including embedding hollow fibers (or microcapsules) filled with healing agents, thermoplastic additives, or dynamic bonds in the epoxy networks. The self-healing mechanisms, advantages, and disadvantages of each method are summarized. Finally, the conclusion and prospect of self-healing epoxy resins are highlighted.
