One-Step Synthesis of the Polyaniline–Single-Walled Carbon Tubes Nanocomposite in Formic Acid and Its Electrochemical Properties

Abstract

A one-step synthesis of a stable dispersion of nanocomposite consisting of polyaniline (PANI) and single-walled carbon nanotubes (SWCNTs) was carried out by the oxidative polymerization of aniline with benzoyl peroxide (PB) in concentrated formic acid (FA). Electrically conductive film coatings were obtained by direct application of this dispersion to an electrode. The coatings have high specific electrochemical capacitance and stability during prolonged cycling in an aprotic electrolyte (1 M LiBF₄ in γ-butyrolactone).
