The scratch healing behavior of different polymers based on reversible interactions was investigated. For this purpose, scratches were induced via femtosecond laser ablation and were analyzed using laser-scanning microscopy. The healing process was monitored over time and the residual scratch volume was studied. Thus, healing kinetics of different self-healing polymers were obtained revealing a new three step-healing process. An initial time is required in order to start the crack closure behavior. Afterwards, a fast healing behavior followed by a final slow healing period could be observed. Consequently, this study discloses significant insights into the time-dependent healing behavior of polymeric materials.

研究了基于可逆相互作用的不同聚合物的划痕愈合行为。为此，通过飞秒激光烧蚀诱导划痕，并使用激光扫描显微镜进行分析。随着时间的推移监测愈合过程并研究残留的划痕体积。因此，获得了不同自修复聚合物的修复动力学，揭示了一种新的三步修复过程。需要一个初始时间来开始裂纹闭合行为。之后，可以观察到快速愈合行为，然后是最后的缓慢愈合期。因此，这项研究揭示了对聚合物材料随时间变化的愈合行为的重要见解。
