Mass transport in intrinsically conducting polymers: Importance, techniques and theoretical models.

In this work we discuss the aspects related to the phenomenon of mass transport in thin electroactive polymer films. Such phenomenon must he considered because the properties and consequent applications of these materials largely depend on the movement of charge carriers, i.e. ions, electrons or holes. The most recent majority of the techniques, methods and theoretical models used in this type of study are gathered and discussed, providing an easy and critical way for choosing the methodology for an investigation.
