Electroactive polymer film dynamics

The electrochemical quartz crystal microbalance is a versatile technique for studying several aspects of electroactive polymer film dynamics. For rigid films, it is a sensitive probe of mobile species (ion and solvent) population changes within the film in response to redox switching. For non-rigid films, it can be used to determine film shear moduli. In the former case, one simply follows changes in crystal resonant frequency. In the latter case, the frequency dependence of resonator admittance in the...

A number of useful reviews have previously been pubUshed. The review by Murray provides a good summary of early work in the area, and reviews by Albery and Hillman and Hillman are also useful. More recent reviews have been written by Abruna, Evans, Smyrl and Lien, Kaner, Pethrick, and on a more general level by Lyons. A monograph on the electrochemistry of electroactive polymers has recently been published under the editorship of Murray.This volume contains a useful chapter by Majda on the dynamics of electron transport in polymeric assemblies of redox centres. In the same volume a chapter coauthored by Oyama and Ohsaka surveys experimental methods used to quantitate transport in electroactive polymer films. There is much useful experimental data tabulated in this work. In the same volume Murray gives a comprehensive overview of the electrochemistry of electroactive polymers, whereas the contribution by...
