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 Mn 0.6 Zn 0.4 Fe 2 O 4 -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 Mn 0.6 Zn 0.4 Fe 2 O 4 -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 Zn 0.4 Fe 2 O 4 -CNTs to aniline ( m (Mn 0.6 Zn 0.4 Fe 2 O 4 -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.
