| 摘 要： | 为实现惯性约束核聚变中无接触点打靶实验构想，探索在聚苯乙烯(PS)中掺杂纳米磁性粉体，以制备磁性靶丸。采用本体聚合工艺制备了Fe3O4/PS磁性靶丸复合材料，通过FTIR、TG-DSC、SEM、VSM等手段对该材料进行了分析表征。结果表明：Fe3O4/PS靶丸复合材料的饱和磁化强度随磁性粉体含量的增加而增大;适量粉体的掺入提高了复合材料的拉伸强度和冲击强度，且随粉体含量的增加而增强;所制备的磁性靶丸复合材料悬浮时所需的外界磁场相对较弱，其磁性能满足磁悬浮的条件。

| Abstract: | The polystyrene ICF target material doped with nanometer magnetic Fe3O4 particle was prepared to fabricate the magnetic target without a support rod used in ICF experiment. The Fe3O4/PS magnetic composite target material prepared by bulk poly-merization process was characterized by FTIR, TG-DSC, SEM, VSM, respectively. As a result, the susceptibility, tensile strength and impact strength of the composite increase with the increasing of the content of nanometer magnetic Fe3O4 particle. The prepared magnetic composite target material can levitate in a weak magnetic field. |

| Keywords: | inertial confinement fusion polystyrene Fe3O4 doping magnetic target material |
