Investigation into Morphology Characterization of Various Surface Electrode of Biopolymer Actuator: Ionic Polymer Metal Composites

Abstract

Focusing on various surface electrode effects on electromechanical properties of biopolymer actuator: ionic polymer metal composites (IPMC), a new laminated structure model, composed with the electrolyte layer, the middle layer and the surface electrode layer, is provided to redefine the composition of IPMC actuator. A failure analysis is performed to study the failure reasons of IPMC actuator. Subsequently, based on various surface electrode of IPMC actuator, the electromechanical properties were further investigated by comparison with the chemical plating samples and the electrophoretic deposition sample. Finally, after the analysis of the morphology characteristics, the improvement mechanism of the various surface electrodes is obtained to further clarify. Results find the electromechanical properties of IPMC actuator is closely attributed to the electrical conductivity of the surface electrode.

Prediction of the Actuation Property of Cu Ionic Polymer–Metal Composites Based on Backpropagation Neural Networks

“…Ionic polymer–metal composites (IPMCs) are an important class of electroactive polymers consisting of a thin layer of ionic polymer film and two layers of metal electrodes. − As shown in Figure , the membrane contains anions (SO 3 – ) connected to the backbone, cations that can freely travel within the membrane, and water molecules. , At applied voltage, the transportation of hydrated cations and water molecules to the cathode leads to the expansion of the membrane on one side of the cathode, which leads to the bending motion of the IPMC sample (Figure ). Because of the low driven voltage, flexibility, biocompatibility, and large deformation, IPMCs have been widely used in different fields such as biomechanical and biomedical applications, robotics, flexible sensing, as well as the aerospace and vehicle industry. − …”
