Abstract
We report a chemical route to synthesize oriented arrays of conducting polyaniline(PANI) nanotubes (60–150 nm in diameter and a few micrometres in length) byhydrogen-bonding directionality in the presence of a crown ether derivative(CE-SO3K) and ammonium persulfate (APS) in HCl solution. The morphology of the oriented PANInanotubes was confirmed by SEM and TEM images. The effects of reaction conditions onthe morphology of the resultant PANI nanostructures were studied. The chemical andelectronic structures of the PANI nanotubes were also studied by FTIR and UV–visspectrometry, respectively.
