| 摘 要： | 提出了一种简便易行的对磁性纳米粒子表面进行氨基化的方法.首先使用化学共沉淀法合成了粒径为10 nm左右的Fe_3O_4纳米粒子,然后用阿仑膦酸钠对其表面进行修饰,使其表面具有了功能化的氨基.利用透射电子显微镜(TEM)、X射线衍射(XRD)、振动样品磁强计(VSM)、动态光散射(DLS)仪、热重分析(TGA)仪、傅里叶变换红外(FT-IR)光谱仪、X射线光电子能谱(XPS)仪等对其进行表征.结果显示磁性纳米粒子表面被成功地修饰了一层双膦酸分子.所制备的纳米粒子可在pH=6.3稳定存在4周以上.

| Abstract: | We propose a convenient method to synthesize surface amino-coated magnetic nanoparticles.Fe3O4 nanoparticles with a grain diameter of about 10 nm were synthesized by the chemical co-precipitation of ferrous chloride and ferric chloride.The obtained superparamagnetic nanoparticles were surface-modified with alendronate to introduce an amino group onto their surfaces.The particles were characterized by transmission electron microscopy (TEM),X-ray diffraction (XRD),vibrating sample magnetometry (VSM),dynamic l... |
