Enhancing mechanical performance of a covalent self-healing material by sacrificial noncovalent bonds
JA Neal, D Mozhdehi, Z Guan - Journal of the American Chemical …, 2015 - ACS Publications
Polymers that repair themselves after mechanical damage can significantly improve their
durability and safety. A major goal in the field of self-healing materials is to combine robust
mechanical and efficient healing properties. Here, we show that incorporation of sacrificial
bonds into a self-repairable network dramatically improves the overall mechanical
properties. Specifically, we use simple secondary amide side chains to create dynamic
energy dissipative hydrogen bonds in a covalently cross-linked polymer network, which can …
