title: Synthesis of Ultralong Polyaniline Nanorods by Magnetic Nanoparticles as Templates Under External Magnetic Field.
abstract: We report the successful synthesis of ultralong polyaniline nanorods (UL-PANI-NRs) via using water-soluble magnetic Fe3O4 nanoparticles as soft templates under the assistance of external magnetic field. It was found that the concentration of Fe3O4 nanoparticles, the aniline concentration and the use of an external magnetic field significantly affect the morphology of the PANI products. The following characterizations including transmission electron microscopy (TEM), Fourier-Transform Infrared Spectroscopy (FTIR), X-ray diffraction (XRD). and thermogravimetric analysis (TGA) were conducted to investigate the electronic structure and composition of as-prepared UL-PANI-NRs. Our preliminary result indicates that complicated polymer structures (such as ultralong rods with vertical branches) may be prepared by water-soluble magnetic Fe3O4 nanoparticles as soft templates under the assistance of alternatively external magnetic fields.
