Shape Retention in Polyaniline Artificial Muscles

Behaviors of polyaniline artificial muscle under high tensile loads have been studied. The artificial muscle based on the electrochemomechanical deformation exhibits a large creep under high tensile loads. However, the creep is recovered by the removal of tensile loads and several electrochemical cycles. The facts indicate that the creep is due to the one dimensional anisotropic deformation. The anisotropic deformation is retained by the ionic crosslink at the oxidized state, and released by the cycling under load free.
