Quartz Crystal Microbalance Studies of Electrochemical Growth of Conducting Polymers
Abstract
In-situ monitoring of the mass change occurring during electrochemical growth of conducting polymers is possible by use of Quartz Crystal Microbalance. The mass change due to polymer formation as well as doping of anions and solvent up-take are monitored with time. Electro-polymerization factors, such as electrolysis mode(galvanostatic, potentiostatic, scan, pulse), electrolyte, solvent are compared and the electrochemistry of the resulting film has been examined. QCM/Potentiostatic measurements have the advantage of providing simultaneous mass change and charge data. From these, 2 distinct growth phases are observed a fast, charge-efficient growth on substrate and a slower, inefficient growth on pyrrole.
