Abstract
Dynamic polymers with remarkable energy dissipation and dampening are highly sought after for advanced applications. Here, spring-like aromatic foldamers were incorporated into the backbones of polymer networks crosslinked with dynamic Diels-Alder (DA) adducts or non-dynamic static crosslinkers. Improved mechanical, self-healing and dampening properties were found in networks with shorter chains, more aromatic stacked foldamer units and dynamic DA adduct crosslinks. These enhanced properties were attributed to the synergistic effects of the reversible elastic response to stress of spring-like aromatic foldamers and the dynamic bonding of DA adducts.
