Abstract
This presentation will summarize our recent advances on H-bond-mediated polymers (HBMPs), fabricated via judiciously tuning the interchain/intersegment H-bonding interactions, in conjunction with rational design of the covalent polymer chain or network structures. We demonstrate that H-bond-mediated assembly offers an effective strategy to fabricate new polymers with unprecedented properties and sustainability, using commodity polymers as building blocks. Importantly, the synergy of multivalence cooperativity and dynamic nature of the H-bonding interactions in HBMPs can reconcile the trade-off between strength and toughness, enabling simultaneous achievement of superhigh strength and superhigh toughness. Moreover, optimizing multivalence cooperativity allows the H-bonded crosslinks to mimic covalent crosslinking, providing thermoset-like stability while maintaining recyclability in thermoplastic polymers.
