CHAPTER 3

Reversible Covalent Bond Formation as a Strategy for Healable Polymer Networks

This chapter outlines several critical aspects of the design of polymer networks containing reversible covalent cross-links for material healing applications. Polymer network architecture and reversible cross-link type are identified as the principle considerations in covalent adaptable network design, as they ultimately dictate how efficiently the material will heal or relax on a macroscopic length-scale. Additionally, several reversible addition- and exchange-type covalent chemistries suitable as cross-links in covalent adaptable networks, as well as strategies to trigger healing reactions, are highlighted. Finally, the dynamic properties of these materials is briefly discussed, highlighting the distinguishing characteristics in comparison with traditional thermoplastics and thermosets.
