Synthesise of CoFe2O4-Polyaniline Nanocomposite and Evaluation of its Magnetic Properties |
|
| چکیده انگلیسی مقاله |
Particles of Cobalt ferrite, CoFe2O4-, were coated with polyaniline (PANI) sulphate and phosphate during in-situ polymerization of aniline in an aqueous solution of sulfuric and phosphoric acid. The PANI-ferrite composites were characterized by Fourier transform infrared (FTIR) spectroscopy. Structures and morphology of products were studied by X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The crystallite size calculated by XRD was 16.65 nm. Magnetic measurement shows that CoFe2O4- and nanocomposite exhibit ferromagnetic behavior. The saturation magnetization, Ms, remanent magnetization Mr and coersivity Hc for PANI sulphate/ CoFe2O4- nanocomposite were 40 emu/g, 20 emu/g and 301 Oe respectively. The same variables for PANI phosphate/CoFe2O4- nanocomposite were 12 emu/g, 28 emu/g and 333 Oe respectively. |
