| Abstract: | Electrochemical bilayer actuators were fabricated from conductive electroactive polymer polypyrrole deposited by electrochemical polymerization. Films of polypyrrole doped with dodecylbenzene sulphonate (PPy-DBS) and with gold coating on one side were prepared by galvanostatic electrochemical polymerization of pyrrole. Polystyrene sheet (used for over-head-projector) with thermally deposited gold film, was used as working electrode. The strong interaction of pyrrole with gold was made use of to get a freestanding polypyrrole film with gold coating on one side (PPy-DBS/Au). Bilayer actuators, were fabricated from these freestanding films and tested in 1 M LiClO₄ solution. The actuator showed bending of up to 90º on both sides on electrochemical reduction/oxidation under an applied potential of 2-3 V. The applied voltage determined the response time, which was 2 to 3 s. The actuator action was also observed with low frequency ac signal. |
