Synthesis and characterization of polyaniline-based nanocomposites containing magnetic Li–Ni–La ferrite

Polyaniline-based nanocomposites containing magnetic Li–Ni–La ferrite were synthesized by a conventional in situ chemical oxidation polymerization. X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) spectra studies indicated the presence of Li–Ni–La ferrite in the nanocomposites. SEM micrographs showed that the nanocomposites exhibited the quasi-spherical morphology. The magnetic measurements indicated that the tuning of magnetic property of resulting nanocomposites was achieved by controlling La substitution content.
