Self-healing polymer coatings are an emerging class of smart materials. Upon mechanical damage the material properties may be restored by self-healing, which can be triggered externally, e.g., by an increased temperature. An alternative approach relies on embedding capsules with repair agents into the polymers, the rupture of which is induced by the mechanical damage, and the release of the repair agents triggers the self-repair reaction. The work at hand presents in situ Raman spectroscopic investigations on the reaction dynamics in such self-healing polymer coatings. Analysis of the Raman spectra allows one to assign specific Raman bands characteristic for the progress of the self-healing reaction.
自修复聚合物涂层是一类新兴的智能材料。在受到机械损伤时，材料性能可通过自修复得以恢复，这种自修复可以由外部因素触发，例如温度升高。另一种方法是将含有修复剂的胶囊嵌入聚合物中，机械损伤会导致胶囊破裂，修复剂的释放触发自修复反应。本文介绍了对此类自修复聚合物涂层中反应动力学的原位拉曼光谱研究。对拉曼光谱的分析能够确定自修复反应进程所特有的特定拉曼谱带。
