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 X-ray 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 Mn0.6Zn0.4Fe2O4-CNTs to aniline (m(Mn0.6Zn0.4Fe2O4-CNTs)/m(An)) is 0.15, the Ms, Mr and Hc 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.
