In this paper, the importance and research degree of self-healing nanomaterials are first introduced, and some methods of self-healing nanomaterials are briefly described, and then some advantages of self-healing technology in nanomaterials compared with traditional nanomaterials are listed. The internal and external factors of self-healing nanomaterials are mainly elaborated. External factors include light-induced self-healing, heat-induced self-healing, and chemical self-healing. Internal factors include dynamic chemical bonding, built-in microcapsules, and nanoparticle migration. By studying the specific reaction processes and mechanisms of each remediation, as well as giving examples of specific materials, the differences between external and internal causes are compared, and the advantages and disadvantages of each are listed. Finally, several applications of self-healing nanomaterials are described, including the application of self-healing pressure sensors and self-healing temperature sensors in smart textiles. It also describes the prospect of the application of self-healing nanomaterials in medical self-healing wearable biosensors and self-healing flexible electronic skin.
