Nanocomposite Films Obtained by Electrochemical Codeposition of Conducting Polymers and Carbon Nanotubes

Abstract

Abstract The electrochemical growth of carbon nanotubes (CNTs) – conducting polymer composites offers the ability to produce three‐dimensional nanostructured films that combine the redox pseudo‐capacitive charge storage mechanism of conducting polymers with the high surface area and conductivity of CNTs [1–3]. In this paper we report the electropolymerization and characterization of polypyrrole films (PPy) doped with poly ( m ‐aminobenzenesulfonic acid) (PABS) functionalized single‐walled carbon nanotubes (SWCNTs) (PPy/CNTs). The negatively charged CNTs served as anionic dopant during the electropolymerization to synthesize PPy/CNTs composite films. Electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV) and scanning electron microscopy (SEM) were used to investigate the electrochemical properties of the composite films.
