“…In the past decade, several authors have focused their attention on the electromechanical transduction properties of IPMCs and models, increasing the number of scientific publications. 31,36,[53][54][55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70][71][72] However, the credit for the first paper in this regard goes to Sadeghipour et al 9 where they described the Nafion® based IPMC as 'smart material'. And stated that the 'smartness' of the Nafion® is based on electrochemical effects.…”

In this paper we present a comprehensive review of ionic polymer metal composite (IPMC) covering fundamentals of IPMC; from fabrication processes to control and applications. IPMC is becoming an increasingly popular material among scholars, engineers and scientists due to its inherent property of low activation voltage, large bending strain, i.e., transformation electrical energy to mechanical energy, and properties to be used as bidirectional material, i.e., it can be used as actuators and sensors. Among the diversity of electro active polymers (EAPs), recently developed IPMCs are good candidates for use in bio-related application because of their biocompatibility. Yet, the challenge remains in controlling a somewhat complicated material as mechanical, electrical and chemical properties interact with each other in the ionic polymer. Several IPMC fabrication processes, their mechanical characteristics and performance, a number of recent IPMC applications and pertaining mathematical modeling have been reported in this paper. Also we have attempted to present concisely the control of IPMC and effects of various factors in the performance of IPMC. The applications of IPMC have been growing, and recently more sophisticated IPMC actuator applications have been performed. This indicates that the IPMC actuators hold potential for more sophisticated control application. Extensive references are provided for more indepth explanation.

“…The obtained tip positions for “zero dehydration” are given in Table 1. The tip angle with dehydration can be obtained as φ = 2 tan − 1 ( p y / p x ) (Bandopadhya and Njuguna, 2009) as shown in Figure 2(a). Similarly, one may obtain the tip angle in “zero dehydration” ( φ 0 ) using the same formula.…”

Theoretical and experimental investigation of dehydration loss of ionic polymer–metal composite actuator is important to evaluate the stability, accuracy, and effectiveness of actuation. An ionic polymer–metal composite actuator of silver electrode has been analyzed to demonstrate the effect of dehydration on vibration characteristics during actuation. Experiment is conducted in cantilever configuration under direct current potential, and the bending and vibration characteristics are measured by Laser Vibrometer. As dehydration occurs during the actuation process, these experimental data are used to establish empirical model for loss-factor in terms of input voltage and time using Cobb–Douglas production method. A correlation is also developed for tip deflection with applied voltage. For theoretical investigation, multimode approximation has been taken into consideration and extended Hamilton’s principle is applied for developing the governing equation of motion of the actuator. Few modes are taken into consideration, and the equations are solved numerically to obtain the transient and steady-state responses of the actuator. Theoretical steady-state results are compared and validated with the experimental results. Both theoretical and experimental results show the gradual reduction of tip displacement due to dehydration.

“…9(a) shows the change in tip position in transverse direction with various input voltages. Figure 9(b) demonstrates the tip deflection of IPMC actuators of various electrode materials, such as IPMC of size 20 Â 5 Â 0.2 mm 3 fabricated by casting method using silver nano-powder [12], gold-plated IPMC of size 40 Â 5 Â 1 mm 3 [17], platinum-plated IPMC of size 35 Â 7 Â 0.2 mm 3 prepared by manual polishing [18], and IPMC fabricated by casting method with platinum as the surface electrode of size 50 Â 15 Â 0.45 mm 3 [19]. It is clearly observed that the developed IPMC exhibits superior performance compared to other surface electrode materials with less power consumption.…”

The proposed work is in line with the evaluation of electro-mechanical and thermal characteristics of silver-electroded ionic polymer–metal composite (IPMC). IPMCs are fabricated first using Nafion-117 as base polymer and non-precious metal silver as surface electrode by chemical decomposition method. Several testings are performed on fabricated IPMC to evaluate its thermo-mechanical and micro-structural properties. The characteristics of the electrode layer and deposited particles on IPMC surface are studied using scanning electron microscope. The bending experiment of the actuator is conducted by applying direct current potential and the tip displacement measured. Thermo-gravimetric analysis and differential scanning calorimetry test are carried out, and thermal stability of the actuator is investigated. The crystal structure of IPMC is investigated by X-ray diffraction analysis. Micro-tensile test of the specimen is carried out to ascertain the stress–strain relationship and comparison is made with the base polymer, Nafion. The experimental investigations, characterization, and performance of the IPMC demonstrate its effectiveness to be used as actuator and artificial muscle materials.
