Notes:
This study dealt with the Maxwell stress effect of waterborne polyurethane (WPU)/conductive filler nanocomposite, which was a promising candidate for a material to be used indielectric elastomer actuator electrode. Conductive nanocomposites were produced by using threetypes of conductive filler such as carbon black (CB), vapor grown carbon fiber (VGCF), and silverpowder (Ag). Among them, conductive nanocomposite containing VGCF exhibited the lowestthreshold concentration. And the blend of CB and VGCF (CB/VGCF) filler had a synergistic effect toelectrical conductivity. Actuation test showed that CB/VGCF nanocomposite electrode had thelargest displacement. Then it could be stated that the improvement of the displacement in CB/VGCFnanocomposite electrode was originated from the increase in relative dielectric constant. In addition, aunique feature of the hysteresis in the bending deformation was described. The feature is that the priorapplication of an electric field significantly improves the bending speed in the successive application
