Waste PET-Derived BHET as a Dynamic Architect for Biobased Self-Healing Polyurethanes with Tunable Strength and Reversible Adhesion
Development of sustainable vitrimers that integrate both high mechanical properties and complete recyclability is still an abiding challenge owing to the conventional trade-off between permanent mechanical strength and network adaptability. In this study, biobased polyurethane vitrimers are synthesized using castor o...
