Abstract

Polyaniline-LiNiferrite (LiNi_0.5Fe₂O₄) nanocomposites were synthesized by in situ aqueous polymerization of aniline in the presence of ferrite. The structure, morphologies and magnetic properties of samples were characterized by X-ray diffraction (XRD), infrared spectra (FTIR), Raman spectra, UV-Vis spectra, transmission electron microscope (TEM) and vibrating sample magnetometer (VSM) techniques. The results indicated that the nanocomposites under applied magnetic field exhibited the hysteresis loops of the ferrimagnetic nature at room temperature. The ferrite particles had the core effect on the polymerization of aniline. The bonding interaction existed between ferrite particles and polyaniline in the composites, and the bonding mechanism was investigated.

Key words: LiNi ferrite, polyaniline, nanocomposite, magnetic property, bonding mechanism
