“…The Lamé parameters of the electrodes are two orders of magnitude larger, that is, 𝐺 e = 5 GPa and 𝜆 e = 30 GPa. With respect to the usual moduli for metals, these are about one order of magnitude lower (Liu et al, 2019), as justified by their significantly larger defectiveness, due to the plating processes adopted in IPMC fabrication (Kim and Shahinpoor, 2003).…”

“…Different layers play different roles in IPMC transduction. [23][24][25][26] A double-layer capacitor C is formed at the interface of the surface electrode and the electrolyte, electrode resistances R sa (R sb ) in lengthdirection and R 1 in thickness-direction are introduced by the surface electrodes, and an internal resistance R 2 is introduced by the electrolyte. A phenomenological model to illustrate the roles of IPMC is also shown in Figure 1(a).…”

“…According to our previous work, 26 the EDX line analysis of metal element for IPMC samples could be used to obtain the thickness of the surface electrodes, and the surface and cross-sectional SEM images as shown in Figure 1(b), segmented by Otsu's thresholding method, can be used to obtain the porosity of the metal electrode of IPMC samples by using ImageJ software.…”

The structural characteristics of ionic polymer-metal composite (IPMC) were analyzed, and the effects of IPMC length ranging from 1 to 5 cm (with a width of 0.5 cm) were evaluated in terms of electrical parameters and actuation behavior. It has been concluded that the electrical parameters of IPMC materials (including capacitance, electrode resistance in thickness-direction, and internal resistance) decrease, and the bending strain of the setpoint increases as the length increases. The simulation of the current response of IPMC to 2 V DC voltage shows that the error between simulated peak current using 1 cm-IPMC parameters and the measured value is 8.23 times higher than that of 5 cm-IPMC. The strain of the set point on 5 cm-IPMC sample is 5.65 times bigger than that of the 1 cm-IPMC sample.

“…Compared with conventional actuation materials, it is endowed with the advantages of lightweight, large strain range, low energy consumption, soft structure, good environmental adaptability, strong affinity, and various functions. [1][2][3][4] IPMC has very broad application prospects in the fields of biomimetic soft robots, medicine, aerospace, and underwater research. 5 For example, Bian et al 6 have designed a bionic mechanical fish drive technology.…”

IPMC is a new type of polymer material that will act violently to the stimulation of electrical signals. IPMC has changed the traditional mechanical driving mode. However, the development of IPMC is limited by factors like manufacture cost. In order to reduce the manufacture cost of IPMC, improve the output displacement and output force of IPMC, and make IPMC closer to real life, in this paper, we use carbon nanotubes to modify the ion exchange membrane of IPMC, and PDDA to modify carbon nanotubes and graphene. A graphite plated electrode and a carbon nanotube electrode were coated on a platinum plated IPMC. The common modified Pt-IPMC, carbon nanotubes modified Pt-IPMC, carbon nanotubes modified GS-IPMC, and carbon nanotubes modified CNT-IPMC were prepared. Through the experiment, it is found that the maximum output displacement of GS-IPMC modified by carbon nanotubes is 4.9 mm, and the maximum output force is 39 mN. The output displacement of ordinary Pt IPMC is 3.18 mm and the maximum output force is 31 mN. The maximum displacement and output force of GS-IPMC modified by CNTs are higher than those of Pt IPMC, which is more suitable for research and application.
