Influence of the Characterization Methodology on the Repair Performance of Self-Healing Materials

Abstract

The repair performance of the so-called self-healing polymer systems has been extensively studied in recent works. However, the characterization methodology carried out to analyze the repair performance of these materials has not been widely discussed. Herein, a study of the influence of the characterization parameters on the self-healing capabilities of a 2-Aminophenyl disulfide (AFD)/epoxy system via convective heating is carried out. Results show a decrease in the self-healing efficiency proportional to the damage depth. Finally, increasing the healing temperature and time does not significantly affect the repair performance, obtaining similar self-healing efficiency values (>>95%) in all cases.
