Controlled Growth of Polypyrrole Thin Films by Polymerization-induced Adsorption

Abstract

Abstract Ultrathin polypyrrole films with a nanometer thickness were prepared by repeating adsorption of polypyrrole from the polymerization solution and washing with organic solvents. The thickness of the polypyrrole film linearly increased by using fresh polymerization mixtures at each adsorption step, as confirmed by quartz crystal microbalance and UV spectroscopy.
