Anisotropic Motion of Electroactive Papers Coated with PEDOT/PSS

Abstract We report on an anisotropic actuation of electroactive papers with a PEDOT/PSS coating in ambient air. PEDOT/PSS‐coated papers were prepared by wetting Manila papers with a concentrated PEDOT/PSS aqueous dispersion and subsequent drying. The electroactive papers displayed a contractile stress when an external voltage was applied, the magnitude and direction of the stress depending on the relative orientation of paper fibers and the loading direction of the coating. We also demonstrated that a butterfly‐like reversible bending motion of the PEDOT/PSS coated paper occurred when the voltage switching between on and off. magnified image
