Preparation of Polystyrene ICF Target Material Mingled With Nanometer Magnetic Fe3O4 Particle

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.
