摘 要: 以苯乙烯为单体,四氧化三铁纳米粒子(Fe3O4)为磁性体,采用超声辐照乳液聚合法制备了PS/Fe3O4复合粒子(1,1.0μm^100.0μm),其结构和磁性能经FT-IR,XRD和VSM表征。结果表明,核壳之间发生了相互作用,Fe3O4和PS分别以单一相反尖晶石和无定型态存在于1中;1具有超顺磁性,饱和强度为8.333 3 emu·g-1。 PS/Fe3O4 composite material(1,1.0 μm ~ 100.0 μm) was prepared by ultrasonically initiated emulsion polymerization using styrene as the monomer and Fe3O4 as the magnetic substance.The structure,phase composition and magnetic property of 1 were investigated by FT-IR,XRD and VSM.The results showed that PS(amorphous) interacted with Fe3 O4 (inverse spinel) in the core-shell structure of 1,which was superparamagnetic with saturation intensity of 8.333 3 emu · g-1.
