▎ 摘　　要

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 approximate to 10 nm. Also, the concentration is shown to depend strongly on the size of the flakes.
