Abstract

Core-shell structured nanocomposites with NiFe2O4 as the magnetic core and polyaniline (PANI) as the conducting shell were prepared. The structural components in the NiFe2O4 and NiFe2O4/PANI were identified from Fourier transform infrared (FTIR) of the samples. The crystalline phase of NiFe2O4 and NiFe2O4/PANI was characterized by X-ray diffraction (XRD). The shape and size distribution of particles were observed by transmission electron microgragh (TEM). The thermal stability of samples was ensured by thermogravimetric analysis (TGA). The magnetic properties were measured by vibrating sample magnetometer (VSM). The results indicated that the resultant composites exhibited good quadrate morphology and uniform size with magnetic and conducting characteristic and high thermal stability.
