Ionic polymer–polymer composites (IP2Cs) are a novel class of all-organic electroactive polymers that can operate both as electromechanical actuators and as sensors. They are an evolution of ionic polymer–metal composites (IPMCs), since the metallic layers, used to realize the electrodes, are substituted by using organic conductors based on PEDOT:PSS.For the IPMC based actuators it is generally reported that solvents different from water can be used to avoid the dehydration phenomenon.Here the possibility to use ethylene glycol and an ionic liquid, 1-ethyl-3-methylimidazolium trifluoromethanesulfonate, as diluents for the IP2C is investigated. Moreover, different materials have been used for the manufacture of the device electrodes and the performances of different organic transducers have been observed and compared.Reported results show that the use of both ethylene glycol and EmI-Tf as the solvent can have beneficial effects both on the working time duration of IP2C and on the corresponding transduction behaviors.
