Abstract
Optimal conditions and improvement methods for electrochemical polymerization of pyrrole (Py) in the presence of sodium p-toluenesulfonate (PTS) as a dopant in water were studied. The electrical and spectral properties of poly-Py (PPy) doped with PTS were compared with those of PPy doped with sodium alkylbenzenesulfonates such as sodium benzenesulfonate (BS), sodium 4-ethylbenzenesulfonate (EBS), sodium 4-n-octylbenzenesulfonate (OBS), sodium dodecylbenzenesulfonate (DBS) and tetraethylammonium p-toluenesulfonate (Et 4 NPTS), prepared under the same polymerization conditions. UV-Vis-NIR absorption spectra were independent of the electrolytes used.
