Delayed crystallization response-inspired waterborne polyurethane with high performance.

ABSTRACT: Waterborne polyurethane elastomers (WPUE), synthesized in aqueous solutions, represent a revolutionary sustainable alternative to thermoplastic polyurethane elastomers (TPUE), which are typically produced using organic solvent. This shift significantly reduces VOC emissions. However, WPUE often lacks the mechanical strength of TPUE produced through traditional synthetic methods, limiting its potential as a sustainable option. Here, we introduce a high-performance waterborne polyurethane elastomer that not only aligns with green chemistry principles but also achieves impressive toughness of 0.959GJ/m³ and strength of 81.8 MPa. This breakthrough is made possible by a self-reinforcement mechanism known as the delayed crystallization response, which arises from a dynamic biphase structure engi
