摘要
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 iron-aminophthalocyanine-coated Fe3O4 hybrid nanospheres are synthesized by a one-step hydrothermal method, and their structures are characterized by IR, XRD, etc. To effectively utilize the excellent magnetic sensitivity of the functional aminophthalocyanine/Fe3O4 hybrid nanospheres, a novel series of flexible Fe3O4@polyimide （PI） composite films have been developed, which is prepared with various Fe3O4/FePe- NH2 nanoparticle loadings. All of the flexible thin films have uniform morphology without any agglomeration, which have been confirmed by the analysis of scanning electron microscope images. The above composite films, which have the higher saturation magnetization and coercivity compared with the corresponding pure Fe3O4/PI films, indicate that the composites can be a candidate to be used as wave-absorbing materials with highperformance.
