Abstract
Hemiaminal poly(ethylene glycol) (PEG)-based organogels are formulated in polymerizable solvents. The dynamic-covalent nature of the solvent-H-bonded hemiaminal crosslinks, together with the modification of the crosslinking density of the organogels allows for temperature-dependent viscoelastic control. The shape of uncured gels can be permanently retained by templated UV-curing of the solvent, offering great promise for complex manufacturing, printing, sealants, and materials repair.
