Abstract

Ionic polymer metal composites (IPMCs) have been the object of intensive research in the last two decades. IPMC actuators promise to find application in medical and industrial settings, where large deformations and low operating voltages are of critical importance. Here, we present a detailed mathematical analysis of IPMC actuation to illuminate the role of counterion size and ionomer-metal composite layers on transient response and back-relaxation. We build on previous work by our group on thermodynamically-consistent modeling of IPMC mechanics and electrochemistry to afford important insight into the physics of actuation across different spatial and temporal scales.
