- Abstract:
- 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 selfhealing
efficiency in polymer films and can also be applied for other scratch self-healing systems, which are based on reversible
dynamic bonds.
