Abstract

Composite films of polypyrrole (PPy) and poly(2-methoxyaniline-5-sulfonic acid) (PMAS) have been electrodeposited from aqueous electrolytes solution consisting of pyrrole and various ratios of dodecylbenzene sulfonic acid (DBS) and PMAS. The obtained PPy(DBS/PMAS) films exhibited different characteristics in water contents, surface morphology and electrochemomechanical deformations (ECMD) depending on the content of PMAS. A film having the content of PPy(95%DBS/5%PMAS) simply showed the large cathodic ECMD with the strain of 6.1% in non-aqueous electrolyte solution of 0.1M tetrabutylammonium chloride/acetonitrile electrolyte. The improvement of cathodic ECMD is conjectured to the large porosity of the composite film. The ECMD behaviors of the films operated in various electrolyte solutions including aqueous solution are also reported.
