惯性约束聚变靶丸材料磁性聚苯乙烯的制备

Fabrication of Magnetic Polystyrene Used as Inertial Confinement Fusion Target Material

聚苯乙烯(PS)是惯性约束聚变(ICF)实验中重要的靶丸材料,磁性聚苯乙烯材料有利于实现靶丸在辐射场中的无接触支撑。本工作以FeCl3、FeCl2和NaOH为原料,在分散剂的作用下,制得均匀分散的棕黑色Fe3O4磁流体,然后与苯乙烯聚合获得Fe3O4-聚苯乙烯磁性材料。激光粒度分布测试结果显示,所得磁流体的粒度小且分布均匀;XRD分析表明,磁流体中无其它杂相存在。此外,还对Fe3O4-聚苯乙烯磁性材料进行了DTA及FTIR分析。分析测试结果表明,采用本工作所设计的方法可合成出Fe3O4-聚苯乙烯磁性复合材料。

Polystyrene （PS） is an important inertial confinement fusion target material. In order to realize the symmetrical fusion by the noncontacted holding methods, the magnetic target material Fe3O4-PS composite was fabricated with FeCl3, FeCl2, NaOH, styrene and organic dispersant. The characteristic of the Fe3O4-PS composite was analyzed by XRD, DTA and FTIR methods. The magnetic PS obtained in present study has the properties of fine crystal, uniformity of component and highness of magnetic performance.
