Abstract

Abstract: The nano-particles of Fe₃O₄were prepared by a chemical co-precipitation method. Astable polymerizable magnetic fluid of nano-Fe₃O₄was obtained by dispersing oleic acid-coated Fe₃O₄nano-particles in styrene as a carrier liquid. Auniformly dispersed system of nano-particles of Fe₃O₄in polystyrene has been acquired by the free radical polymerization of polymerizable magnetic fluid. The crystallization behavior and the surface of Fe₃O₄nano-particles before and after the modification by oleic acid were investigated by WXRD and FTIR, respectively. The particle size and size dispersion of Fe₃O₄nano-particles in styrene and polystyrene were studied by TEM. The glass transition temperature (T_g) and the thermal stability of nano-Fe₃O₄/polystyrene dispersion system were also studied by means of DSC and TGA, respectively. The results indicate that the nano-Fe₃O₄is a cubic crystal, the particle size is 10 nm on an average, the oleic acid molecules are chemically adsorbed on the surface of Fe₃O₄nano-particles, the modified Fe₃O₄nano-particles are dispersed homogeneously in styrene and in polystyrene. The temperature at sharp weight loss of polystyrene containing only 1.8% Fe₃O₄nano-particles is 13 Khigher than polystyrene and its saturation magnetization is 17. 43 emu/g.
