چکیده مقاله:
Particles of Cobalt ferrite, CoFe۲O۴-, 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 ۱۶.۶۵ nm. Magnetic measurement shows that CoFe۲O۴- and nanocomposite exhibit ferromagnetic behavior. The saturation magnetization, Ms, remanent magnetization Mr and coersivity Hc for PANI sulphate/ CoFe۲O۴- nanocomposite were ۴۰ emu/g, ۲۰ emu/g and ۳۰۱ Oe respectively. The same variables for PANI phosphate/CoFe۲O۴- nanocomposite were ۱۲ emu/g, ۲۸ emu/g and ۳۳۳ Oe respectively.
