Electrochemically driven actuation of polypyrrole in aqueous sodium hexafluorophosphate
(NaPF6) solution has been shown to produce repeated large strains (> 6%) at low voltages
and with high conductivity, making it one of the most promising electroactive conducting
polymers. Little is known about the voltage dependent stiffness of this version of the polymer.
This information is important in determining the strain as a function of load. In this paper the
complex Young's modulus (storage and loss components) of a hexafluorophosphate-doped …
