The Structure of Silver Modified Flexible Graphene Electrodes for Actuators in Biomimetic Systems

Abstract

We present a novel model for semiquantitative estimation of optimal concentrations of silver modifier necessary to increase the conductivity of graphene electrodes in actuators with electroactive polymers and to ensure long-term performance of the system. The model predicts approximately equal masses of silver and graphene in the electrodes after the reduction for the characteristic size of graphene flakes ∼10 nm. Also, the concentration is shown to depend strongly on the size of the flakes.
