摘　　要：摘要：简要叙述了纳米铁氧体的吸波机理，对比了气相法、固相法以及液相法制备镍锌铁氧体的优缺点。重点分析了镍锌铁氧体中Ni^2＋含量对NixZn1-xFe2O4形貌以及电磁性能的影响。得出结论，Ni^2＋含量对NixZn1-xFe2O4形貌不会产生明显影响，但Ni^2＋含量x为0．6时NixZn1-xFe2O4表现出最好的吸波性能。另外有研究表明铁氧体与碳纳米管、石墨烯的复合存在可能并能一定程度提高铁氧体电磁性能，提出将碳纳米管、石墨烯与Ni0.6Zn0.4Fe2O4复合制备高性能复合吸波材料的方案。Briefly describe the nano ferrite absorbing mechanism, Compared the advantages and disadvantages of the preparation of Ni-Zi ferrite by gas phase method, solid phase method and liquid phase method.The effect of Ni^2＋ content on morphology and electromagnetic properties conclusion that Ni^2＋ content won＇t produce significant of NixZn1-xFe2O4 are emphatically analyzed.Draw a effect on the morphology of NixZn1-xFe2O4, but NixZn1-xFe2O4 have the best wave absorption performance when ＇x＇ is 0.6.Moreover, studies have shown that there exist possibility for ferrite composites with carbon nanotubes and graphene, what＇ s more, electromagnetic properties of ferrite is improved to some degree, so the article propose a scheme to compositecarbon nanotubes and graphene with Ni0.6Zn0.4Fe2O4 to synthesis anew material with excellent wave absorbing performance.
