Self-Healable and Microstructure-Programmable Vitrimeric Nonisocyanate Polyurethane Foams via Decoupled Fabrication
The intrinsic kinetic coupling between cross-linking and foaming presents a fundamental challenge for the production of nonisocyanate polyurethane (NIPU) foams, limiting independent control over their microstructure and properties. Here, we report a sequential fabrication strategy that decouples these processes to pr...
