Notes:
Interpenetrating polymer networks (IPNs) have been developed for many years leading tomaterials with controlled properties. When an electronic conducting polymer (ECP) is incorporatedinto an IPN, this one becomes a conducting IPN (CIPN). The synthetic pathway ensures a nonhomogeneous dispersion of the ECP through the IPN thickness of the material. The system is thussimilar to a layered one with the advantage that the intimate combination of the three polymersneeds no adhesive interface. The last step in making the CIPN into an actuator is to ensure the ionicconductivity by incorporation of an ionic salt. The highest ionic conductivity through the IPN matrixis necessary in order to ensure the best actuation. The chosen salt is an ionic liquid, i.e. 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMImTFSI). Based on IPN architectureselectrochemical actuators have been designed and actuation in open air has been characterized
