Microphase regulation via benzotriazine-siloxane synergistic construction realizes highly stretchable and self-extinguishing polyurethane elastomers for flexible sensors

Key Points

• The aim is to enhance the recyclability and fire resistance of polyurethane elastomers for better industrial use.
• Developed a novel construction method combining benzotriazine and siloxane
• Assessed properties of elastomers including stretchability and flammability
• Conducted tests for flexible sensor applications
• Achieved significant improvements in stretchability compared to traditional PU elastomers
• Demonstrated self-extinguishing properties under flame exposure
• Enhanced recyclability supports sustainable industrial practices
