Abstract

Abstract: Uniform P(St-co-AA) microspheres were prepared by microemulsion polymerization. The Fe₃O₄/P(St-co-AA) microspheres with a high magnetic content were prepared by electrostatic self-assembly using P(St-co-AA) microspheres with Fe₃O₄nanoparticles synthesized by co-precipitation. The effects of pH, stirring on the preparation of Fe₃O₄/P (St-co-AA) were investigated. All samples were characterized by transmission electron microscope (TEM), scanning electron microscope(SEM), X-ray diffraction(XRD), FTIR spectroscope. The magnetic property of the obtained magnetic powder with Fe₃O₄ single phase was tested by VSM. The results indicate that the average sizes of polymer microspheres P(St-co-AA) with carboxyl and the magnetic powders Fe₃O₄ are 70nm and 10nm, respectively. Magnetic property measurement shows that the saturated magnetization of the magnetic powders is 69A·m²·kg^-1 when the applied field is up to 1.5×10⁶/pi(A/m) at room temperature. The assembled Fe₃O₄/ P(St-co-AA) with an average size of 800nm is spherical and the content of magnetic powders is 15.8％.

Key words: Fe₃O₄, P(St-co-AA) microspheres, self-assembly, magnetic microsphere
