| 摘 要： | 采用在纳米Fe3O4颗粒表面通过引入过氧基因引发甲基丙烯酸甲酯(MMA)聚合的方法,在纳米Fe3O4颗粒表面接枝了PMMA.采用傅立叶红外光谱(IR-FT)检测粉体表面官能团,采用X射线光电子能谱(XPS)检测粉体表面化学键变化,采用高分辨透射电镜(HRTEM)观察改性后粉体的表观形貌.结果表明纳米Fe3O4呈球形,颗粒间团聚不明显,在纳米Fe3O4表面成功地包覆了PMMA,PMMA以化学接枝的方式结合在Fe3O4颗粒表面.

| Abstract: | peroxide group was introduced onto the surface of Fe_3O_4 to initiate MMA to polymerize at last we gained magnetic Fe_3O_4 nanoparticles grafting modified. Surface group, Surface chemical bond and appearance of modified and unmodified nanoparticles were characterized by FT-IR, XPS and HRTEM. The result is that Fe_3O_4 nanoparticles are spheres and the reuniting between nanoparticles was not evident, Fe_3O_4 nanoparticles are coated by PMMA in the form of chemical grafting. |
