| 摘 要： | 在阳离子表面活性剂(CTAB)胶束体系中制备立方相Co_3O_4磁性纳米粒子,将其与制备原液的混合体系分散到阴离子表面活性剂十二烷基苯磺酸钠(SDBS)溶液中,再加入苯乙烯引发聚合,制得聚苯乙烯/Co_3O_4复合纳米粒子.TEM观察Co_3O_4纳米粒子的平均粒径为30 nm左右,复合纳米粒子的粒径为40 nm左右.XRD、IR谱图及热、磁性能测定表明聚苯乙烯对Co_3O_4纳米粒子的包裹是成功的.

| Abstract: | Cubic Co_3O_4 magnetic nanoparticles can be prepared in the cationic surfactant micellar system of CTAB.The mixed solution spread around into anionic surfactant of SDBS and styrene.Adding some initiator to this reaction mixture,composite nanoparticles polystyrene/Co_3O_4 were obtained.The com- posite nanopatricles is shelled by polystyrene and pitted by Co_3O_4 nanopatricles.The diameter of Co_3O_4 nanoparticles is about 30 nm and that of the composite nanoparticles is 40 nm.The results of XRD and FT-IR spectra showed that the enwrapping of polystyrene with Co_3O_4 nanoparticles was successful. |
