This presentation will highlight recent advances in our investigation of stimuli-responsive materials that rely on reversible covalent interactions. By constructing branched macromolecules and hydrogels that are crosslinked via dynamic-covalent bonds, we are able to prepare materials capable of responding to changes in their surrounding environment. Single chains and polymeric nanoparticles that contain these linkages are able to reconfigure their macromolecular structure and/or dissociate into smaller components by reshuffling their covalent crosslinks. Hydrogels crosslinked via reversible linkages are able to heal themselves by crosslink exchange across their failure interface. This presentation will cover our recent results in each of these areas.
