摘要：

With an average diameter of 100-150nm, composite nanotubes of polyaniline (PANI)/multiwalled carbon nanotubes (MWNTs) containing Fe3O4 nanoparticles (NPs) were synthesized by a two-step method. First, we synthesized monodispersed Fe3O4 NPs (d = 17.6 nm, sigma = 1.92 nm) on the surface of MWNTs and then decorated the nanocomposites with a PANI layer via a self-assembly method. SEM and TEM images indicated that the obtained samples had the morphologies of nanotubes. The molecular structure and composition of MWNTs/Fe3O4 NPs/PANI nanotubes were characterized by Fourier transform infrared spectra (FTIR), energy dispersive X-ray spectrometry (EDX), X-ray photoelectron spectra (XPS), X-ray diffraction (XRD) and Raman spectra. UV-vis spectra confirmed the existence of PANI and its response to acid and alkali. As a multifunctional material, the conductivity and magnetic properties of MWNTs/Fe3O4 NPs/PANI composites nanotubes were also investigated. (C) 2008 Elsevier Inc. All rights reserved.
