thermal and magnetic characteristics of cellulose acetate- fe3o4

fe3o4 nanoparticles were synthesizedviaa 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.
