The State of Art of Electrode Interface of Ionic Polymer-Metal Composites (IPMC)

As a type of emerging smart materials, ionic polymer-metal composites (IPMC) consisting of polymer matrix and metal electrodes have a good electromechanical conversion capability. It can be made into a variety of actuators and sensors easily, which show great potentials in various fields. Mechanical and electrical properties of IPMC are affected by many factors, among which the electrode interface is one of the important factors. This paper reviews domestic and foreign research works on the electrode interface characteristics of IPMC in recent years, summarizes the main methods to optimize the electrode interface and proposes an effective design ideas to improve the preparation process of electrode interface of IPMC.
