摘要：

Polyaniline (PANI) films were polymerized on glass carbon (GC) electrodes with small molecular dopantshydrochloric, perchloric, sulfuric, methanesulfonic, benzenesulfonic, rho- toluenesulfonic and large macromolecular size poly(4-styrenesulfonic (PSS)), poly(vinylsulfonic), poly(acrylic), and poly(anilinesulfonic) acids. Theredox electroactiveswere studied in buffered solutions with the pH of 3, 5, 7, and 9. Results indicated that the properties PANI films were strongly dependent on the molecular size and polar characteristics of the dopants. With the polyelectrolytes, it was found that the PANI doped with PSS showed a good redox behavior, and maintained the inherent electro activity of PANI in the neutral and even in alkaline media.
