Controlled Synthesis of Y-Junction Polyaniline Nanorods and Nanotubes Using In Situ Self-Assembly of Magnetic Nanoparticles
Abstract:Novel Y-junction polyaniline (PANI) nanorods and nanotubes (40–100 nm in diameter and a few micrometers in length) were selectively prepared, for the first time, using in situ self-assembly of water-soluble Fe3O4 nanoparticles coated with polyethylene glycol(5) nonylphenyl ether (NP5) and cyclodextrin (CD) as templates and pH control in an aqueous medium. The morphology of Fe3O4 nanoparticles and the PANI nanostructures (rods and tubes) was determined by TEM and the effects of reaction conditions on the morphology of PANI nanostructures were also studied. Characterization experiments including FTIR and X-ray diffraction were carried out to study the chemical and electronic structures of the PANI nanostructures.
