Abstract

Polyaniline nanoparticles were prepared on a highly oriented pyrolytic graphite (HOPG) surface from dilute polyaniline acidic solution (1 mM aniline + 1 M HClO₄) using a pulsed potentiostatic method. Electrochemistry, Fourier transform infrared external reflection spectroscopy (FT-IR-ERS), X-ray photoelectron spectroscopy (XPS) and tapping-mode atomic force microscopy (TMAFM) were used to characterize the composition and structure of the polyaniline nanoparticles. FT-IR-ERS and XPS results revealed that the polyaniline was in its emeraldine form. TMAFM measurement showed that the electropolymerized polyaniline nanoparticles dispersed on the HOPG surface with a coverage of about 10¹⁰ cm^-2. These nanoparticles were disk-shaped having a height of 10-30 Å and an apparent diameter varying from 200 to 600 Å. The particle dimensions increased with the electropolymerization charge (Q) over the interval from 5.7 to 19.3 μC cm^-2. (C) 2000 Elsevier Science S.A.
