Abstract Leather surface is easily scratched and then discarded somewhere, which might result in a great waste of resources and economics. Self-healing materials could efficiently solve this problem. In this study, furfuryl alcohol (FA) and bismaleimide (BMI) were introduced to polyacylate for preparing self-healing polyacrylate emulsion (PA/(FA-BMI)), which was used as a finishing agent in leather process. Fourier transform infrared spectroscopy indicated that Diels-Alder reaction had taken place between FA and BMI. The dynamic light scattering, transmission electron microscopy and scanning electron microscopy results showed that FA and BMI were dispersed uniformly in polyacrylate. Thermogravimetric analysis results indicated that the addition of FA and BMI increased the thermal stability of polyacrylate. The ultra depth of field microscope (UDFM) results showed that the damaged PA/(FA-BMI) could be self-healing completely when the amount of FA and BMI was 5 %. The leather after finishing with PA/(FA-BMI) could be fully self-healing in 5 h at 50 °C. PA/(FA-BMI) endowed the finished leather good self-healing performance towards scratches on the surfaces. Meanwhile, physical and mechanical properties of the leather finished by PA/(FA-BMI), such as tensile strength, tear strength, wet and dry rub resistance, were also improved obviously.

与呋喃醇接枝双马来酰亚胺交联的聚丙烯酸酯：一种自修复聚合物涂层

摘要 皮革表面很容易被划伤然后随处丢弃，这可能会造成资源和经济上的极大浪费。自修复材料可以有效地解决这个问题。在本研究中，将糠醇（FA）和双马来酰亚胺（BMI）引入聚酰化物制备自修复聚丙烯酸酯乳液（PA/（FA-BMI）），在皮革加工中用作整理剂。傅里叶变换红外光谱表明FA和BMI之间发生了Diels-Alder反应。动态光散射、透射电镜和扫描电镜结果表明 FA 和 BMI 均匀分散在聚丙烯酸酯中。热重分析结果表明，FA和BMI的加入提高了聚丙烯酸酯的热稳定性。超景深显微镜(UDFM)结果表明,当FA和BMI的用量为5%时,受损的PA/(FA-BMI)可以完全自愈。PA/(FA-BMI)整理后的皮革可以在50°C下5小时内完全自愈。PA/(FA-BMI)赋予成品皮革对表面划痕具有良好的自愈性能。同时，PA/(FA-BMI)整理后的皮革的拉伸强度、撕裂强度、干湿摩擦性等物理机械性能也有明显提高。
