“…The result shows that the elastic modulus of the newly produced Ag-IPMC is less than 23 MPa, and the elastic modulus increased negatively as the moisture content decreased. The elastic modulus achieved 139 MPa when the moisture content dropped to 1.09% [68]. On the other hand, Poisson's ratio increased from 0.42 to 0.49 with an increase of water content from 0% to 15%.…”

“…Using a universal testing machine in a tensile mode and dynamic mechanical analysis (DMA) in a shear mode, it was found that Au-IPMCs have the highest tensile strength (56 MPa) and modulus of elasticity (602 MPa) in dried conditions (Table 1). In another study, Xu et al [68] studied Ag-IPMC and the impact of water content on the elastic modulus and Poisson's ratio of the Ag-IMPC material. The result shows that the elastic modulus of the newly produced Ag-IPMC is less than 23 MPa, and the elastic modulus increased negatively as the moisture content decreased.…”

Recent Progress on Electroactive Polymers: Synthesis, Properties and Applications

Electroactive polymers (EAPs) are an advanced family of polymers that change their shape through electric stimulation and have been a point of interest since their inception. This unique functionality has helped EAPs to contribute to versatile fields, such as electrical, biomedical, and robotics, to name a few. Ionic EAPs have a significant advantage over electronic EAPs. For example, Ionic EAPs require a lower voltage to activate than electronic EAPs. On the other hand, electronic EAPs could generate a relatively larger actuation force. Therefore, efforts have been focused on improving both kinds to achieve superior properties. In this review, the synthesis routes of different EAP-based actuators and their properties are discussed. Moreover, their mechanical interactions have been investigated from a tribological perspective as all these EAPs undergo surface interactions. Such interactions could reduce their useful life and need significant research attention for enhancing their life. Recent advancements and numerous applications of EAPs in various sectors are also discussed in this review.

“…Its biomimetic bending response makes it an ideal material for use in human-machine integrated technologies, active skin, and artificial muscles. [7][8][9] For example, Ma et al 10 successfully developed a biomimetic Forsythia suspensa based on an IPMC driver and simulated the natural opening and closing process of Forsythia suspensa. Ming et al 11 developed an intelligent glove based on IPMC sensing, which can be widely used in the field of pulse monitoring.…”

“…Although IPMC has excellent performance and special functions, in practice, there are still many limitations, such as the high water sensitivity-its action will decrease in a dry environment-and the smaller output force and short service life, and its output capacity is related to thickness [8]. IPMC is easy to fail; in the period of time after its use, IPMC will lose its activity, and at the same time, there will be many irreversible changes in its structure, and it will lose its effectiveness of motion.…”

With the development of bionics and marine science, a new artificial muscle material, IPMC (ion-exchange polymer metal composite), has attracted significant attention. However, the performance issues, as well as problems associated with the preparation of IPMC, have limited its development. In this study, we use the freeze-drying technique, successfully creating a new type of enhanced carbon nanotube IPMC material. Moreover, we also use the method of cyclic voltammetry, ac impedance, and the constant current charge and discharge method to analyze and evaluate the multiwalled carbon nanotube (MWCNT)-reinforced IPMC produced by freeze-drying technology. Freeze-dried IPMC has a higher moisture content, which is 1.58 times higher than that of ordinary IPMC. The pore and multiwalled carbon nanotube (MWCNT) in the ion exchange membrane are distributed more homogeneously. The technology prepared by IPMC has superior electrical performance. Under a 2 v scanning interval and a scanning speed of 50 mV/s, its specific capacitance can reach 247.5335 mF/cm−2, which is 24 times that of normal IPMC. Under the same conditions, its conductivity can reach 0.29391 mS/cm, far higher than that of ordinary IPMC. Furthermore, the preparation process is also safer. This method provides a new strategy for the future preparation and usage of IPMC.
