Preparation of magnetic-conductive Mn0.6Zn0.4Fe2O4-CNTs/PANI nanocomposites through hydrothermal synthesis coupled with in situ polymerization

A facile chemical method through hydrothermal synthesis coupled with in situ polymerization to prepare the Mn0.6Zn0.4Fe2O4-carbon nanotubes (CNTs)/polyaniline (PANI) nanocomposites has been reported in this paper. The structure of samples has been characterized by the Fourier transform infrared and Xray diffraction. The shape and size of samples have been observed by the scanning electron microscopy and transmission electron microscopy. The conductive properties of the Mn0.6Zn0.4Fe2O4-CNTs/PANI nanocomposites have been tested by a four-probe conductivity tester at room temperature. And the magnetic properties are measured by a vibrating sample magnetometer. When the mass ratio of the Mn-0.6-Zn0.4Fe2O4-CNTs to aniline (m(Mn0.6Zn0.4Fe2O4-CNTs)/m(An)) is 0.15, the M-s, M-r and H-c achieves 15.44 emu/g, 5.06 emu/g and 308.68 Oe, respectively. At the same time the probable formation mechanism of nanocomposites is also investigated based on the experimental results. (C) 2014 Elsevier Ltd. All rights reserved.
