Research progress of self‐healing polymer materials for flexible electronic devices

Abstract Self‐healing polymer materials have been a research hotspot in the field of smart materials since their invention. They have self‐diagnostic functions and are capable of self‐healing small cracks. By applying self‐healing materials to flexible electronic devices, the mechanical damage caused by bending, folding and scratching of these devices can be reduced. The reliability and service life of the devices could be improved accordingly. This paper provides a brief overview of self‐healing polymers and focuses on their applications in flexible electronic devices. In addition, this paper prospects the future development and challenges of self‐healing polymer materials.
