Polyaniline nanofibers: chemical synthesis using surfactants†
Abstract
Nanofibers of doped polyaniline.HCSA having diameters 1–2 nm are observed in TEM images of bath sonicated aqueous dispersions of larger nanofibers (30–50 nm diameter) synthesized by surfactant-assisted chemical oxidative polymerization of aniline in dilute aqueous organic acids.
