Within the current study, a novel approach for the detailed determination of the scratch healing efficiency in mussel-inspired polymer films is presented. For this purpose, a sensor molecule was incorporated into a self-healing polymer network based on reversible zinc–histidine interactions. The fluorescence of the sensor molecule was monitored enabling a detailed depth- and time-resolved determination of the healing efficiency by means of confocal laser scanning microscopy (CLSM). Finally, this concept represents an efficient and detailed approach for the determination of the scratch self-healing efficiency in polymer films and can also be applied for other scratch self-healing systems, which are based on reversible dynamic bonds.

共轭低聚物作为荧光标记，用于测定贻贝启发性聚合物的自愈效率

在当前的研究中，提出了一种新颖的方法，用于详细确定贻贝启发的聚合物薄膜中的划痕愈合效率。为了这个目的，基于可逆的锌-组氨酸相互作用，将传感器分子结合到自愈聚合物网络中。通过共聚焦激光扫描显微镜（CLSM）监测传感器分子的荧光，从而实现深度和时间分辨的愈合效率测定。最后，该概念代表了一种有效而详细的方法，用于确定聚合物薄膜中的划痕自我修复效率，并且还可应用于基于可逆动态键的其他划痕自我修复系统。
