摘　　要：利用溶胶-凝胶自蔓延方法制备铁氧体(BaFe12O19)磁性纳米粒子;利用悬浮聚合的方法制备带有酰胺基的聚苯乙烯-丙烯酰胺/铁氧体磁性颗粒(NMP)。利用XRD、FTIR、磁强计、扫描电镜(SEM)、元素分析仪对NMP的颗粒基质晶体结构、饱和磁化强度、表面官能团和微观结构等进行表征。BaFe12O19 nano - particles were prepared by sol - gel self - propagating method. PSi - acrylamide/ferrite magnetic particles were synthesized by suspension method. Magnetic particles were successfully prepared. XRD, FTIR, JMD - 13 VSM, SEM and Elemental analysis were used to characterize the crystal structure, saturation magnetization, functional group, micro- structure of NMP respectively.
