A Waterborne Epoxy Vitrimer: Enabling Moisture-Driven Actuation, Continuous Moist-Electric Generation, and Water-Assisted Degradation.

ABSTRACT: The integration of multiple hydroxyl structures presents a robust strategy for designing epoxy vitrimers based on transesterification reactions (TERs), enabling the realization of optimal dynamic properties. Nevertheless, significant challenges persist in achieving eco-friendly synthesis, hydrophilic-related functionalities, and sustainable degradation. Here, a catalyst-free waterborne epoxy vitrimer is developed by curing 1,4-butanediol diglycidyl ether with natural L-tartaric acid (L-TA), effectively addressing these challenges simultaneously. Harnessing the synergistic effects of multiple hydroxyl groups and the neighboring group participation effect imparted by L-TA, the resulting vitrimer exhibits rapid stress relaxation (τ^* = 270 s at 190 °C) and undergoes complete degrada
