With an average diameter of 100-150 nm, composite nanotubes of polyaniline (PANI)/multiwalled carbon nanotubes (MWNTs) containing Fe{sub 3}O{sub 4} nanoparticles (NPs) were synthesized by a two-step method. First, we synthesized monodispersed Fe{sub 3}O{sub 4} 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/Fe{sub 3}O{sub 4} 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/Fe{sub 3}O{sub 4} NPs/PANI composites nanotubes were also investigated. - Graphical abstract: The work on preparing nanocomposites has been too much, but few reports were about synthesizing one-dimensional nanocomposite of three different nanoscale materials. In our work, we prepared one-dimensional multiwalled carbon nanotubes/Fe{sub 3}O{sub 4} particles/polyaniline composite nanotubes and studied their conductive and magnetic properties.
