▎ 摘　　要

Operation features of actuators based on the domestic electroactive polymer MF-4SK in combination with graphene electrodes is first studied. This system demonstrates several advantages, e.g. better mutual adhesion of materials, over those employing conventional flexible metal electrodes and Nafion membranes. The reported model of electroactive polymers connects sizes and structure of water-filled pores to geometrical characteristics of polymers with the goal of comparing properties of MF-4SK and Nafion polymers.
