CuS nanoparticles are introduced into a thermoreversible polyurethane based on Diels-Alder (DA) bonds and disulfide bonds,successfully yielding a self-healing polyurethane with five-fold response to thermal,near-infrared light,microwaves,solar light,and UV. When the CuS content is 0.3% (mass fraction),the modified polyurethane achieves optimal comprehensive mechanical properties and self-healing performance. After damage such as cracks or fractures in the modified polyurethane occurs,the material can be restored repeatedly through heat-treated at 120 ℃ for 6 min,irradiated with 4 W/m2 of near infrared light at a wavelength of 808 nm for 60 s,or treated under a 250 W microwave for 80 s,and followed by a heat treatment for 12 h at 60 ℃. In addition,the damaged sample can also be repaired multiply after being treated to a simulated solar light or irradiated through UV for 6 h. The results show that the near-infrared light response offers the quickest self-healing speed,shortest repair time and highest repair efficiency. The self-healing behavior is achieved through the cooperation of thermoreversible DA reaction,disulfide bonds exchange,dissociation and regeneration of hydrogen bonds,directional migration of CuS nanoparticles,and thermal movement of molecular chains. These findings have important guidance for the development of multi-responsive self-healing materials with efficient self-healing capability and provide various ideal selections for damage repair under different environments.

将硫化铜纳米粒子引入基于Diels-Alder(DA)键和双硫键的热可逆聚氨酯中,成功得到具有热、近红外光、微波、太阳光和紫外光(UV)五重刺激响应的自修复聚氨酯。当硫化铜添加量为0.3%(质量分数)时,改性聚氨酯的综合力学性能和自修复性能达到最优。改性聚氨酯在出现裂纹、裂缝等损伤后,通过在120 ℃处理6 min或在4 W/m2波长为808 nm近红外光照射60 s或经250 W微波作用80 s,随后分别于60 ℃处理12 h便可实现损伤的多次良好修复。此外,损伤试样经模拟太阳光或UV照射6 h后,也能实现多次自修复。结果表明:近红外光响应修复速度更快、修复时间最短、修复效率最高。自修复是通过热可逆DA反应、双硫键交换、氢键的解离和再生、CuS纳米粒子的定向迁移以及分子链的热运动五种作用协同实现。上述研究结果对于开发具有高效多重响应自修复材料具有重要的指导意义,为材料在不同使用环境下的损伤修复提供了多种理想选择。
