摘要
在共沉淀法制备Fe3O4纳米磁粉的基础上,以丙烯酰胺(AM)为单体,在水溶液中通过电子束辐照的方法,制备了具有核壳结构的磁性复合微球Fe3O4/PAM.采用XRD、AFM、IR等对样品进行表征.结果表明,制备的磁粉为Fe3O4单相,粒径为8nm左右,磁性高分子微球Fe3O4/PAM直径约为100nm,呈球形.分析了单体浓度、磁粉用量、交联剂浓度、辐照剂量等对Fe3O4/PAM微球粒径的影响规律.
Magnetic nanoparticles were perpared by the chemical coprecipitation of ferrouschloride and ferricchloride. Fe3O4/PAM core-shell composite magnetic particles were synthesized by EB-irradiation and characterized by XRD, AFM, and FTIR. The results indicate that the only product prepared by cooperation method was single-phase Fe3O4 and its diameter was about 8 nm. The microsphere was spherical and its diameter was about 100 nm. It has been found that the diameter of the core-shell microparticles can be controlled by changing Fe3O4 and doses of irradiation. concentration of monomer AM, magnetic nanoparticles
