Electrochemically Initiated Chain Polymerization of Pyrrole in Aqueous Media

摘要

The electrochemical quartz crystal microbalance has been employed to investigatethe electropolymerization of pyrrole in a variety of aqueous electrolytes. In contrast to the generally accepted cation-radical coupling process for the electropolymerization of pyrrole, an electrochemically initiated chain polymerization, featuring a high polymerization rate and involving little charge transport, was found under specific conditions in the presence of ClO4-BF4-, and
