Three-Dimensional Charge Redistribution of Ionic Polymer-Metal Composites with Uncertainty in Surface Conductivity

Abstract:

In this paper, the three-dimensional charge redistribution of IPMC material under dynamic electric potentials with uncertainty in surface conductivity is studied. The governing equations of charge redistribution are derived from the Nernst-Planck equation, the Poisson equation, the mass conservation equation and the basic electrostatic equations. The surface conductivity is viewed as a Gaussian distribution. A travelling wave type analytical solution is obtained to account for the three-dimensional cation movement under the applied electric potentials.
