基于超分子氢键动态网络的高强度自修复弹性体材料的制备与性能研究
Preparation and Properties Study of High-strength Self-healing Elastomers Material Based on Supramolecular Hydrogen-bonded Dynamic Networks
摘要
Abstract
A novel self-healing polyurethane-urea elastomer was designed by leveraging the reversible,dynamic network of supramolecular hydrogen bonds,with 4,4′-diaminobenzanilide(DABA)serving as the chain extender.The amino groups of DABA react with isocyanate to form rigid segments,while its aromatic backbone and strong urea-type hydrogen bonds enhance mechanical performance.The resulting elastomer exhibits an outstanding tensile strength of 7.15 MPa and excellent elasticity,achieving a healing efficiency of 99.5%after 30 min at 90℃.The study offers a facile strategy for fabricating high-performance,self-healing polyurethane-urea elastomers.关键词
