Abstract:
In this study, we report the synthesis of sustainable polyisoxazolines using a vanillin-derived bifunctional nitrile oxide monomer in metal-free nitrile oxide cycloaddition polymerization under mild conditions. The bioderived polyisoxazolines have high biomass contents in high yields with tunable glass transition temperatures. The furan-containing polyisoxazoline could also be cross-linked by using dynamically exchangeable bonds to yield a circular material that can be easily reprocessed for multiple cycles after use. The material’s circularity was demonstrated by encapsulating a thermoelectric generator, which could be recycled easily to obtain the original generator and polymer for device refabrication, showing potential in reducing electronic waste in green electronic applications.
