In this study, Cu-Ionic polymer metal composites (Cu-IPMC) were fabricated using the electroless plating method. The properties of Cu-IPMC in terms of morphology, water loss rate, adhesive force, surface resistance, displacements, and tip forces were evaluated under direct current voltage. In order to understand the relationship between lengths and actuation properties, we developed two static models of displacements and tip forces. The deposited Cu layer is uniform and smooth and contains about 90% by weight of copper, according to the energy-dispersive X-ray spectroscopy (EDS) analysis data obtained. The electrodes adhere well (level of 5B) on the membrane, to ensure a better conductivity and improve the actuation performance. The penetration depth of needle-like electrodes can reach up to around 70 μm, and the structure shows concise without complex branches, to speed up the actuation. Overall the maximum displacement increased as the voltage increased. The applied voltage for the maximum force output is 8–9 V. The root mean square error (RMSE) and determination coefficient (DC) of the displacement and force models are 1.66 and 1.23, 0.96 and 0.86, respectively.

Based on the biological characteristics of tulip, the low driving voltage and fast response of ionic polymer metal composite (IPMC), we analyzed the fabrication, morphology and performance of the platinum IPMC (Pt-IPMC) and selected the right IPMC for driving bionic tulip. The preparation and performance of IPMC was analyzed first in this paper such as blocking force, output displacement and bending angle of IPMC under the different directed current voltage (DC). The optimal IPMC sample size and driving voltage were selected based on tulip blooming angles and the strain energy density of IPMC, which completed the blooming process of bionic tulip. The feasibility of IPMC used in driving bionic field was fully proved in this paper, which laid a foundation for the application of IPMC in driving biomimetic biological robots.

New Applications

IPMCs are one of the most promising smart actuators to replace traditional actuators for some specific applications particularly in the micro-nano scales. IPMC actuator’s shape and configuration have a dramatic effect on the actuation parameters. While the behaviour of IPMCs as a single fixed end strip actuator (cantilever) has been widely studied since the early 80’s, its behaviour in other configurations is relatively unknown. This paper presents work carried out in order to reconfigure these actuators for some new applications. The first configuration is when both ends of an IPMC actuator strip are fully constrained, in both the actuator plane and the normal direction. In this case the displacement and force measurements at the mid point of the strip are presented. The results of a series of experiments show the behaviour of the actuator in this configuration and using these results some models have been proposed. The second configuration is when only one end of the strip is fixed and the other end is constrained in the normal direction with respect to the plane of the actuator strip. A series of experiments were also carried out to explore the IPMC actuator behaviour in terms of maximum displacement and force generated in this configuration. The behaviour of the IPMC actuator in these two configurations is also investigated by studying the internal stresses in the IPMC structure.

Novel ionic polymer-metal composites (IPMC) based on sulfonated polyimide (SPI) was firstly developed by employing a more convenient, time-saving and effective electroless plating method. Their overall structure and the distribution of metal particles in the membranes were examined by scanning electron microscopy (SEM) attached with energy dispersive X-ray spectrometer (EDS). The actuation of the prepared IPMC was evaluated. The analytical results confirmed that platinum are successfully deposited on the membrane. Under DC voltage excitation, the IPMC undergo larger displacement compared with Nafion-based actuators. The larger displacement of the IPMC was considered to be the result of the higher concentration of sulfonyl groups, larger ion exchange capacity, and consequent larger volume of water moving.

During the last decades, the ionic polymer-metal composite (IPMC) received much attention because of its potential capabilities, such as large displacement and flexible bending actuation. In this paper, a biomimetic flapping air vehicle was proposed by combining the superiority of ionic polymer metal composite with the bionic beetle flapping principle. The blocking force was compared between casted IPMC and IPMC. The flapping state of the wing was investigated and the maximum displacement and flapping angle were measured. The flapping displacement under different voltage and frequency was tested. The flapping displacement of the wing and the support reaction force were measured under different frequency by experiments. The experimental results indicate that the high voltage and low frequency would get large flapping displacement.

Solution Casting Technique

As an ionic electroactive polymer, ionic polymer metal composite (IPMC) has unique advantages and is widely used in various fields. However, the output force of IPMC is small, which further limits the application of IPMC. In this study, the Nafion520cs were selected as the preparation solution, and three ion-exchange polymer membranes (IEPMs) with different thicknesses (158, 256 and 383 [Formula: see text]m) were designed and prepared successfully by solution casting technique to study the output force. Then, three platinum electrodes-IPMCs (Pt-IPMCs) were fabricated using electroless plating method. The properties of Pt-IPMCs in terms of morphology, displacements and blocking forces were then evaluated under direct current voltage. The results showed that the prepared ionic membranes were uniform, transparent and flat, without accumulation or bubble. The platinum particles were preferably deposited on the surface, which promoted delivery of current through the IPMCs under the applied voltage, and improved the actuation performance. With the increase of voltage, the maximum displacement and maximum blocking force of the three IPMCs increased first and then decreased. When the voltage is 5.5 V, the maximum displacement for 158 um is 26 mm, while the maximum blocking force of 10.74 mN appears at 6.5 V for 383 um. It is necessary to select suitable thickness of IPMCs to adapt to different working environment and field, which provides a strong basis for further application of IPMCs.

Nafion membrane with macropores is synthesized from silica crystal and composited with Pt nanoparticles to fabricate macroporous ionic polymer-metal composite (M-IPMC) actuator. M-IPMC shows highly dispersed small Pt nanoparticles on the porous walls of Nafion membrane. After the electromechanical performance test, M-IPMC actuator demonstrates a maximum displacement output of 19.8 mm and a maximum blocking force of 8.1 mN, far better than that of IPMC actuator without macroporous structure (9.6 mm and 2.8 mN) at low voltages (5.8–7.0 V). The good electromechanical performance can be attributed to interconnected macropores that can improve the charge transport during the actuation process and can allow the Pt nanoparticles to firmly adsorb, leading to a good electromechanical property.

Bending Response

After obtaining a way to fabricate IPMC actuator with palladium electrodes, the deformation of IPMC actuator behavior is evaluated under various solvents, various temperatures, and various frequencies of input voltages. By using the non-electrolytic plating method to obtain IPMC actuator, it is found that as the increase of the ionic radius the bending response of IPMC actuator becomes predominant from the experimental observation. When the electric field across its cross section is unloaded, IPMC actuator shows a large back relaxation under high temperature. In the experiment of the frequency response of the input voltage, IPMC actuator shows a good response to various frequencies from 0.1 to 6.0 Hz in which the resonant peak is observed at 5.5 Hz.
