“…Although the volumetric work density value of the IPMC with 20 wt% was quite close to the value of the 10% sample, the former showed more advantages in higher WUP and less cost. As summarized in Supplementary Materials Table S1 (Supporting Information) , the displacement and blocking force are higher than those of other types of bending actuator, at a 2 V DC voltage as well as 0.1 and 1 Hz square-wave activation for PEO/Nafion-IPMC with 20 wt% PEO [ 2 , 33 , 34 , 35 , 36 , 37 ]. However, the blocking force of IAEP-IPMC [ 2 ] is higher than that of PEO/Nafion-IPMC, as a result of the high-quality metal electrodes of the former actuator fabricated via the isopropanol-assisted electroless plating.…”

Current ionic polymer-metal composite (IPMC) always proves inadequate in terms of large attenuation and short working time in air due to water leakage. To address this problem, a feasible and effective solution was proposed in this study to enhance IPMC performance operating in air by doping polyethylene oxide (PEO) with superior water retention capacity into Nafion membrane. The investigation of physical characteristics of membranes blended with varying PEO contents revealed that PEO/Nafion membrane with 20 wt% PEO exhibited a homogeneous internal structure and a high water uptake ratio. At the same time, influences of PEO contents on electromechanical properties of IPMCs were studied, showing that the IPMCs with 20 wt% PEO presented the largest peak-to-peak displacement, the highest volumetric work density, and prolonged stable working time. It was demonstrated that doping PEO reinforced electromechanical performances and restrained displacement attenuation of the resultant IPMC.

“…Through parameter editing, the equipment can prepare IPMC sensors with silver electrode of different shapes. After plasma treatment on the matrix surface, Esmaeli et al sputtered a layer of titanium or chromium between the gold electrode and Nafion matrix [Figure 4A], which further improved the adhesion between the electrode and the ionomer [68] .…”

Ionic polymer metal composite (IPMC) transducers, as one of the typical electroactive polymers with excellent electromechanical coupling properties, have tremendous potential to achieve high-performance actuators and sensors for flexible electronic and soft robotics. In this survey, after briefly describing the energy conversion mechanism of IPMC, we divided the history of IPMC into three stages based on the published papers, and then introduced the preparation technologies of IPMC in detail, which mainly include the selection of ionomer membrane and formation of electrodes. From the point of view of optimization, we summarized and analyzed the performance improvement methods of IPMC and the problems when it is used as actuators and sensors, respectively. The latest and typical applications of IPMC are widely presented as actuators and sensors, such as actuation in robots, grippers, medical and wearable devices, underwater perception and energy harvesting. Moreover, the challenges and opportunities of IPMC were envisioned for future prosperity. This survey will provide an overall general outline for the categorization, mechanism, precursors, and preparation methods of IPMC, which is helpful in facilitating the rapid development and application of IPMC.

“…The electrode is a vital part of IPMC, and it has two main functions: One is to act as a carrier of applied voltage and conduct current; the other is to form a capacitor with the intermediate layer that can accommodate a certain amount of charge [ 32 ]. The surface resistance of the electrode can directly affect the output performance of IPMC; thus, in the preparation process of IPMC material, in order to reduce the surface’s resistance of the electrode, a thin membrane electrode will be plated on the outside of the initially formed electrode [ 33 ].…”

As a new type of flexible smart material, ionic polymer-metal composite (IPMC) has the advantages of being lightweight and having fast responses, good flexibility, and large deformation ranges. However, IPMC has the disadvantages of a small driving force and short lifespan. Based on this, this paper firstly analyzes the driving mechanism of IPMC. Then, it focuses on the current preparation technology of IPMC from the aspects of electroless plating and mechanical plating. The advantages and disadvantages of various preparation methods are analyzed. Due to the special driving mechanism of IPMC, there is a problem of short non-aqueous working time. Therefore, the modification research of IPMC is reviewed from the aspects of the basement membrane, working medium, and electrode materials. Finally, the current challenges and future development prospects of IPMC are discussed.
