采用水热法一步制备氨基铁酞菁包覆的Fe_3O_4的磁性纳米微球,并采用红外、XRD等对其结构进行表征。利用其端氨基接枝共聚到聚酰亚胺主链结构中,使其形成一系列Fe_3O_4/Fe Pc-NH_2/PI复合柔性薄膜(Fe_3O_4@PI)。采用扫描电子显微镜(SEM)观察发现,无机纳米微球在树脂中具有较好的分散性,同时复合薄膜具有较高的饱和磁化强度,有潜力作为高性能吸波材料。
The nano-microspheres of Fe_3O_4 coated with aminophthalocyanine were prepared by hydrothermal method and their structures were characterized by IR and XRD. A series of Fe_3O_4 / Fe Pc-NH_2 / PI composite flexible films (Fe_3O_4 @ PI) were formed by graft copolymerization of the terminal amino groups into the main chain of polyimide. Scanning electron microscopy (SEM) observation shows that the inorganic nanospheres have good dispersibility in the resin, meanwhile, the composite film has higher saturation magnetization and has the potential as a high-performance absorbing material.
