摘　　要：以P123胶束作为"纳米反应器",采用水溶液法合成了Fe3O4纳米粒子。采用场发射扫描电子显微镜(FE-SEM)、X射线衍射仪(XRD)、傅立叶变换红外光谱(FTIR)和样品振动磁强计等现代化分析测试手段对产物的形貌、结构和磁性进行了测试表征。结果表明,合成的Fe3O4纳米粒子粒径大小在30～120nm可控,它们在常温下是超顺磁性的且具有较高的饱和磁化强度。所合成的纳米铁氧体磁性材料在信息存储、生物医药和催化等领域具有重要的理论研究价值和广阔的应用前景。The Fe3O4 nanoparticles are synthesized through a water solution method by using P123 micelles as ＂nano-reactors＂.Their morphologies,structures and magnetism are characterized by some modern analytic measurements of FE-SEM,XRD,FTIR and VSM.The experimental results show that the synthesized Fe3O4 nanoparticles＇ spherical and homogeneous sizes are nearly 30~120 nm.They possess super paramagnetism at normal temperature with a higher saturation and magnetization.The synthesized nano-ferrite magnetic materials have a important theoretical research value and potential application in fields of high-density magnetic recording,biomedicine and catalyst.
