自修复聚合物涂层是一类新兴的智能材料。在机械损伤时，材料性能可以通过自我修复来恢复，这可以在外部触发，例如，因为温度升高另一种方法依赖于将具有修复剂的胶囊嵌入聚合物中，其破裂由机械损伤引起，并且修复剂的释放触发自修复反应。手头的工作提出了在原位拉曼光谱调查的反应动力学在这样的自愈合聚合物涂层。拉曼光谱的分析允许人们分配特定的拉曼带特性的自愈反应的进展。
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.
