Abstract

This comparative study investigates the role of side-group chemistry in mono-sulfonic acid dopants—CSA, DBSA, and TFMSA—within PANI/PAAMPSA complexes. The structural variations among the dopants significantly influenced the polymer-dopant interactions, which in turn altered key material properties. These findings provide molecular-level insights for developing highly stretchable, conductive, and autonomously self-healing materials for flexible and wearable applications.
