Abstract

The differences in protonation and charge transfer behavior between polypyrrole(PPY) powders and films doped with inorganic acids, or bulky acids, were assessed quantitatively by the X-ray photoelectron spectroscopic (XPS) technique. PPY-dodecylsulfate and PPY-toluene-4-sulfonate films with [N+]/[N] ratio over 40% can be readily prepared electrochemically. Treatment of these salt films with a base results in the 25% deprotonated PPY. UV-visible light spectroscopy shows little difference in structures of PPY formed chemically and electrochemically.
