• behavior was also quantified in detail using an indenter. Keywords: characterization of polymers; π–π-interactions; self-healing polymers; supramolecular polymers; Introduction Damage inflicted on different materials is omnipresent. Consequently, nature established a mechanism dealing with this problem

• previous studies, several of these interactions were already applied such as metal–ligand interactions [13][14], hydrogen bonds [15][16] or halogen bonds [17]. Furthermore, π–π interactions also feature a reversible behavior and were therefore utilized for the design of different self-healing polymers [18
