Abstract

Elongation and contraction of polypyrrole and poly(3-methoxyaniline-5-sulfonate) (PMAS) composite films induced upon electrochemical oxidation and reduction, viz., electrochemomechanical deformation (ECMD) are studied. The composite films were electrochemically prepared in electrolyte solutions of pyrrole and dodecylbenzene sulfonic (DBS) acid with a presence of PMAS acid. The contents of DBS and PMAS were varied. Films which were obtained at higher contents of PMAS, were gel like due to a lot of water content. The change of film length due to ECMD was measured as functions of various electrolytes in either aqueous or organic solvents. The results indicated that films exhibited both cathodic and anodic expansions depending on the bulkiness of cations and anions as well as the content of PMAS.
