“…Herein, we introduce a few examples. For example, it has been used for the characterisation of the platinum-coated ionic polymer-metal composites (IPMCs) with aqueous and ionic liquid (IL) electrolytes (Bennett et al, 2006;Shahinpoor and Kim, 2001), for IEAP materials with bucky-gel electrodes (Biso et al, 2013;Ceseracciu et al, 2011;Sugino et al, 2009;Takeuchi et al, 2009), with other carbonaceous electrodes (Kwon and Ng, 2014;Palmre et al, 2011), electroactive interpenetrating polymer network actuators (Festin et al, 2014) and conducting polymer actuators (CPAs; Biso et al, 2012;Temmer et al, 2013).…”

We have developed a technique to determine the bending strain of ionic electroactive polymer actuators without the use of the macroscopic bending geometry. In situ comparisons of the scanning electron microscope micrographs from a bending ionic electroactive polymer actuator, using a digital image correction methodology, identify its bi-directional deformation field. The developed technique allows verification of the factual axial and thickness strains of any notional layer of the actuator, including the outer surfaces of the electrodes. Thus, calculation of the bending and thickness strains of the ionic electroactive polymer laminate becomes possible. Moreover, the technique allows the determination of the position of the neutral layer of bending that is an important requirement for the calculation of the second area and bending moments of the beam. The four examples presented demonstrate the potential variations of the bending schemes, in cases where the neutral layer is at the centroid and shifted away from the centroid.

“…Conventional polymers that appear to be leading candidates for the actuators include poly(vinylidene fluoride) (PVdF)-based polymers [12][13][14][15] , conjugated polymers 16,17 and perfluorinated ionomers with random inclusions of acidic moieties (that is, Nafion) [18][19][20] . To facilitate actuation response to a given voltage, additional solvents have typically been incorporated in these polymers 21 .…”

Fast low-voltage electroactive actuators using nanostructured polymer electrolytes

Electroactive actuators have received enormous interest for a variety of biomimetic technologies ranging from robotics and microsensors to artificial muscles. Major challenges towards practically viable actuators are the achievement of large electromechanical deformation, fast switching response, low operating voltage and durable operation. Here we report a new electroactive actuator composed of self-assembled sulphonated block copolymers and ionic liquids. The new actuator demonstrated improvements in actuation properties over other polymer actuators reported earlier, large generated strain (up to 4%) without any signs of back relaxation. In particular, the millimetre-scale displacements obtained for the actuators, with rapid response (o1 s) at sub-1-V conditions over 13,500 cycles in air, have not been previously reported in the literature. The key to success stems from the evolution of the unique hexagonal structure of the polymer layer with domain size gradients beneath the cathode during actuation, which promotes the bending motion of the actuators.

“…They have been characterized for electromechanical actuator applications, [15][16][17][18] as well as electrode materials for electrochemical capacitors specially due to the high electrical conductivity, high pseudocapacitance, and relatively low cost [19,20]. However, the considerable volume change of the electrode films caused by the intercalation and depletion of ions during the reversible charge and discharge process resulted in a poor mechanical stability in advanced battery and supercapacitor applications [18,21,22].…”
