【 摘 要 】

In the presence of modified Ferro ferric oxide, PMMA/Fe3O4microspheres have been successfully synthesized via a facile suspension polymerization. The effect of modified Fe3O4on the preparation of Fe3O4/PMMA microspheres was investigated by X-ray diffraction (XRD), the morphology of magnetic microspheres was studied by Scanning electron microscope (SEM). Thermal performance of magnetic polymer microspheres was studied by Thermo gravimetric (TG). From the above, with the increase of modified iron oxide, the magnetic polymer microspheres have enhanced magnetic properties and heat resistance.
