A Quartz Microbalance Study of the Electrosynthesis of Polypyrrole
Abstract
An electrochemical quartz crystal microbalance has been used to study the anodic electro-polymerization of pyrrole and concurrent deposition of polypyrrole onto gold in acetonitrile and propylene carbonate using tetraethylammonium tosylate, tetrabutylammonium fluoroborate, and lithium perchlorate. Simultaneous dynamic measurements of charge and mass have been used to monitor the efficiency of the polymerization/deposition process as a function of film thickness and electrodeposition rate. This work demonstrates that the early stages of film formation is affected by the solubility of the oligomers formed and that the ultimate efficiency is electrolyte dependent. Additionally, it is shown that the polymerization process exhibits second order reaction kinetics with respect to monomer concentration.
