摘要

通过向聚氨酯分子链中引入多级氢键与酰腙键，制备了一种可回收的高强自修复聚氨酯。以聚四氢呋喃醚二醇为软段，以4

4′-二环己基甲烷二异氰酸酯，含多级氢键和酰腙键的扩链剂为硬段，通过逐步聚合得到聚氨酯材料。一方面，合成的聚氨酯分子链中的多级氢键赋予材料自修复性能，并且可以调控其力学性能；另一方面，在酸性条件下动态共价键酰腙键可以断裂，进而实现聚氨酯材料的降解与再生资源化。结果表明，在35 ℃，24 h条件下，聚氨酯材料的修复效率可达到91.6%，通过原位变温红外对自修复机理进行了探究。进一步研究了自修复聚氨酯材料的降解性能，有助于实现聚合物的再生资源化与碳资源高效回收，推动高分子材料全生命周期减污降碳协同增效。

Abstract

A self-healing polyurethane which can be degradable was prepared by introducing hierarchical hydrogen bonds and acylhydrazone bonds into the polyurethane molecular chains. On one hand

the hydrogen bonds between chains provided self-healing function for polyurethane. On the other hand

the pH-responsive acylhydrazone bonds endowed materials with recyclable properties. With the increase of the content of acylhydrazone bonds in polymer chains

the mechanical properties of the material were enhanced

and the tensile strength increased from 23.9 MPa to 54.3 MPa. Mechanical performance tests showed that polyurethane materials exhibited good healing performance

with a healing efficiency of 91.6% at 35 ℃. The self-healing mechanism was explored through variable temperature Fourier transform infrared (FTIR) spectroscopy. The polymer materials with self-healing and recyclable properties are significant for the reduction of waste for future low-carbon society.
