Abstract

Polypyrrole films were generated on high purity aluminum substrates under anodic polarization from aqueous electrolytes comprised of pyrrole and sodium dodecylbenzene sulfonate. The methods employed to characterize the polymer films included scanning electron microscopy, Fourier-transform infrared and Xphotoelectron spectroscopy and X-ray diffraction. PPY/SDBS films revealed nodular morphology with occasional appearing of “dendrites”, high level of protonation, excess of counter-anions ([S]/[N] > [N+]/[N]) and high degrees of disorder.

Keywords

Polypyrrole films, aluminium, electrosynthesis
