Abstract

A polypyrrole (PPy)–zigzag metal wire composite film actuator, prepared electrochemically from a methyl benzoate solution of tetrabutylammonium trifluoromethanesulfonate (TBACF₃SO₃), showed up to 21.4% electrochemical strain, much larger than that (12.8%) of the corresponding PPy–CF₃SO₃⁻, driven in aqueous NaPF₆ solution.
