Abstract

Aqueous dispersions of poly(3,4-ethylenedioxythiophene)/poly(4-styrenesulfonate) (PEDOT/PSS) with various PSS composition ratios (α) were newly synthesized and electromechanical properties of the PEDOT/PSS solid films were investigated for the applications to high-strain electro-active polymer (EAP) actuators. The electrical conductivity showed a maximum of 210 S/cm at α = 3, while the degree of water vapor sorption increased with increasing both α and relative humidity (RH). The EAP actuating behavior of the PEDOT/PSS solid films demonstrated that the film contraction attained as high as 7.8% at α = 15 and 70% RH which was more than three times higher than that of the commercial grade of PEDOT/PSS (2.4% at 50% RH).
