Compared to conventional actuators, the soft ionic polymer–metal composite (IPMC) actuator has significant advantages in specific applications, and the mathematical model of IPMC actuators is essential to comprehending and applying IPMCs. Due to the inherent characteristics of IPMCs and the impact of the manufacturing and measurement processes, it is challenging to developa reliable model. This article provides a comprehensive overview of the developments in IPMC actuator modeling. In particular, three types of models are examined and contrasted: the nonphysical identification model, the partial‐physical model, and the physical‐based model. In order to comprehend the current state of numerous IPMC actuator models, the characteristics, evolution, and functions of each type of model are discussed. Afterward, the evolution of the IPMC actuators’ applications is discussed. Finally, promising research directions for IPMC actuator models are identified that can more effectively facilitate the development of IPMC‐based devices.

Ionic polymer metal composites (IPMC) with dendritic interfacial electrodes (DIEs) have attracted attention in recent years due to their excellent actuation performance. Although considerable efforts have been made to develop aggregation models of metal particles for the electrode formation of IPMC, there are few reports to simulate the growth of DIEs inside IPMC. In this work, we proposed an electrode model based on diffusion-limited aggregation (DLA) method to simulate the growth process of DIEs inside IPMC by referring their preparation parameters and morphology characteristics. Meanwhile, the effects of immersion reduction (IR) cycles, immersion electroplating (IEP) time, IEP cycles, current intensity and voltage amplitude on the morphology and microstructure of DIEs inside IPMC were studied. It was found that the depth and the density of DIEs inside IPMC gradually increased with the increase of IR cycles, IEP time and IEP cycles. However, the growth depth of DIEs inside IPMC decreased significantly with the increase of current intensity. In addition, the voltage amplitude has little effect on the DIEs. This model is of great significance to the study of the formation mechanism of IPMC with DIEs.

The growing concern over low-frequency noise pollution resulting from global industrialization has posed substantial challenges in noise attenuation. However, conventional acoustic metamaterials, with fixed geometries, offer limited flexibility in the frequency range adjustment once constructed. This research unveiled the promising potential of ionic electroactive polymers, particularly ionic polymer–metal composites (IPMCs), as a superior candidate to design tunable acoustic metamaterial due to its bidirectional energy conversion capabilities. The previously perceived limitations of the IPMC, including slow reaction and high energy expenditure, owning to its inherent sluggish intermediary ionic mass transport process, were astutely leveraged to expedite the attenuation of low-frequency sound energy. Both our experimental and simulation results elucidated that the IPMC can generate voltage potentials in response to acoustic pressure at frequencies significantly higher than those previously established. In addition, the peak absorption frequency can be effectively shifted by up to 45.7% with the application of a 4 V voltage. By further integration with a microperforated panel (MPP) structure, the developed metamaterial absorbers can achieve complete sound absorption, which was continuously tunable under minimal voltage stimulation across a wide frequency spectrum. In addition, a microslit structure IPMC metamaterial absorber was designed to realize modulation of the perforation rate, and the absorption peak can be shifted by up to 79.2%. These findings signify a pioneering application of ionic intelligent materials and may pave the way for further innovations of tunable low-frequency acoustic structures, ultimately advancing the pragmatic deployment of both soft intelligent materials and acoustic metamaterials.
