Abstract
Nanofillers play a crucial role in designing high-strength polymer materials but contribute less to extensibility and often complicate processing. This paper presents a new strategy for developing polymer composites with outstanding tensile strength, extensibility, and processability, driven by the slip-transfer effect of cation−π interactions between nanofillers and polymer chains. These composites belong to a class of fusible, stiff polymers with excellent mechanical properties. The indole groups on the polymer chains can slip over the K+-functionalized fillers due to dynamic interactions, characterized by the continuous dissociation and reconstruction of cation−π interactions between the indole groups and K+ under an external force. This mechanism imparts exceptional extensibility to the polymer composites. Additionally, the slip-transfer effect enhances the processability of these composites.
