Abstract

An electrochemomechanical device formed by a bilayer polypyrrole-non conducting polymer one side tape was studied in different concentrations of LiClO₄ aqueous solution. The artificial muscle was submitted to a constant anodic current of 15 mA or constant potential of 1000 mV vs. SCE. Chronoamperograms and chronopotentiograms were recorded meanwhile the free end of the bilayer crossed over an angle of 90 degrees. The consumed charge was constant whatever the electrical or chemical conditions were. The electrical energy consumed by the device movement decreased, at increasing concentrations of electrolyte, under galvanostatic control. The consumed energy remains constant under potentiostatic control but times required to cross over the 90 degrees decrease from 20 seconds to 6 seconds.
