Electroactive polymers with sulfur-nitrogen backbones

This work investigates a series of novel electroactive polymers composed exclusively of sulfur and nitrogen in their backbones. The primary aim was to explore new functional groups within inorganic electroactive polymers (EAPs) and assess their electrochemical performance relative to conventional systems. Using a three-electrode setup with polymer films dropcast onto conductive glass, six sulfur-nitrogen backbone polymers (A–F) were analyzed via cyclic voltammetry at varying scan rates (10, 20, 50, and 100 mV/s). Key properties such as redox activity, peak current behavior, ion conductivity, and capacitive characteristics were measured. The study demonstrates the versatility of sulfur-nitrogen backbones in supporting electrochemical activity and highlights their potential for future energy storage and sensing applications. Ongoing work will explore colorimetric changes under applied potential and performance in four-terminal sensing configurations to refine conductivity measurements.
