Summary: Conductive nanotubes were fabricated by the alternate adsorption of negatively charged polypyrrole (PPy) and positively charged poly(allylamine hydrochloride) (PAH) onto the inner pores of polycarbonate templates. Nanotubes are obtained by the subsequently removal of the template. Using several microscopic and spectroscopic techniques, we demonstrate that the yielded materials possess a tubular structure and conductive properties. The conductivity of PPy/PAH nanotubes is measured as 0.008 S · cm −1 .SEM image of eight bilayer PPy/PAH nanotubes after the removal of the template.
