“…Ionic EAPs are commonly composed of a polymeric network (neutral or a polyelectrolyte matrix) loaded/soaked with electrolytes (including ionic liquids (ILs)) and/or carbon nanotubes (CNTs). Examples of this class of actuator include: conducting polymer actuators [ 9 , 12 ], ionic-polymer metal composite (IPMC) actuators [ 13 , 14 ] and CNT actuators [ 15 , 16 ].…”

Electroactive polymers (EAPs), materials that present size/shape alteration in response to an electrical stimulus, are currently being explored regarding advanced smart devices, namely robotics, valves, soft actuators, artificial muscles, and electromechanical sensors. They are generally prepared through conventional techniques (e.g., solvent casting and free-radical polymerization). However, non-conventional processes such as those included in additive manufacturing (AM) are emerging as a novel approach to tune and enhance the electromechanical properties of EAPs to expand the scope of areas for this class of electro-responsive material. This review aims to summarize the published work (from the last five years) in developing EAPs either by conventional or non-conventional polymer processing approaches. The technology behind each processing technique is discussed as well as the main mechanism behind the electromechanical response. The most common polymer-based materials used in the design of current EAPs are reviewed. Therefore, the main conclusions and future trends regarding EAPs obtained by conventional and non-conventional technologies are also given.

Herein, the movement of hydrated cations in ionic–polymer metal composite (IPMC) is analyzed by the micromechanics method. Based on the mechanism of IPMC, the migration of hydrated cations is in a step‐by‐step order, and the aggregation of hydrated cations on the cathode side results in the bending of IPMC toward the anode. The physical models of the maximum displacement and maximum blocking force of IPMC are established, the Pt IPMCs are prepared by chemical deposition, and the calculated values are compared with the experimental values. The results indicate that there is water electrolysis in the actuation process of IPMC, which inhibits the migration of ions on the electrode surface and has a negative effect on the property of IPMC. By comparing the calculated value of the model with the experimental value, it is found that there is good consistency. The mathematical statistical metrics, mean absolute error, mean relative error, determination coefficient, correlation coefficient, mean square error, root mean square error, and relative root mean square error, are used to assess the model capability, which puts a theoretical foundation for the prediction and simulation of IPMC and promotes the further development and practical application of IPMC.

“…This composite lm is oen called an ionic polymer metal composite (IPMC), which is considered to be one of the popular types of articial muscles. [13][14][15][16][17] Due to the special solid/liquid two-phase structures inside Naon, it has a natural affinity for moisture due to which it undergoes a large volume change when it is exposed in a humid environment, as shown in Fig. 1b.…”
