In the past decade,
the self-healing elastomers based on multiple
hydrogen bonding have attracted ample attention due to their rich
chemical structures, adjustable mechanical properties, fast healing
speed, and high healing efficiency. Through prolonging the service
life and fast recovery of the mechanical properties, self-healing
elastomers can be potentially applied in the field of wearable electronics,
electronic skins, motion tracking, and health monitoring. In this
perspective, we will introduce the concept and classification of self-healing
materials first, then the hydrogen bonds, and the corresponding position
of hydrogen-bonding units in the polymer structures. We will also
conclude the potential application of hydrogen bonding-based elastomers.
Finally, a summary and outlook will be provided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
