| 摘 要： | 以聚丙烯酰胺 (PAM) 为表面活性剂，采用一步水热法合成了超顺磁性Fe3O4纳米粒子，并且在改变PAM用量的条件下合成了囊状的磁性材料。通过X射线衍射(XRD)、扫描电子显微镜 (SEM)、振动样品磁强计等对磁性Fe3O4的结构、形貌、磁性进行表征。结果表明，磁性微囊外径约为200 nm，组成微囊的Fe3O4纳米粒子其粒径分布在30 nm左右，磁性微囊的饱和磁化强度为62.5 emu/g，表现出超顺磁性。

| Abstract: | Superparamagnetic Fe3O4 nanoparticles, using polyacrylamide as surfactant, are synthesized by one-step hydrothermal method. And then the sacciform magnetic material is obtained by changing the dosage of surfactant. The structure, morphology and magnetism property of the samples are characterized via X-ray diffraction (XRD), scanning electron microscope (SEM) and vibrating sample magnetometer. The results show that the outside diameter of the magnetocapsules is about 200 nm. The size of Fe3O4 nanoparticles, composing the magnetocapsules, is about 30 nm. The magnetocapsules manifests a superparamagnetism, and the saturation magnetization intensity of the magnetocapsules is 62.5 emu/g. |
