Abstract

The syntheses of conducting copolymers of thiophene-functionalized polystyrene and pyrrole (PS/PPy) were achieved using p-toluene sulfonic acid (PTSA) as the supporting electrolyte via constant potential electrolysis technique. Characterization of the samples was performed by a combination of techniques: cyclic voliammetry (CV), thermogravimetric analysis (TGA), differential scanning colorimetry (DSC), scanning electron microscopy (SEM), NMR, and FT-IR analyses. The conductivities were measured by the four-probe technique.
