Abstract :
Fe3O4 nanoparticles were synthesized via a simple chemical
reaction between FeCl2.4H2O and Fe(NO3)3.9H2O under nitrogen
atmosphere at room temperature, and then nanoparticles were added
to cellulose acetate (CA) polymer. The influence of nanoparticles
on the thermal properties of CA polymeric matrix was studied using
thermogravimetric analysis (TGA). Nanostructures were
characterized by X-ray diffraction (XRD), scanning electron
microscopy (SEM) and Fourier transform infrared (FT-IR)
spectroscopy. The magnetic properties of the samples were also
investigated using an alternating gradient force magnetometer
(AGFM). We found that the Fe3O4 nanoparticles exhibit a
ferromagnetic behavior with a saturation magnetization of 59 emu/g
and a coercivity of 105 Oe at room temperature.
