采用溶胶凝胶法制备了Ni-Cu-zr替代的M型钡铁氧体BaFe12-x(Ni0.5 Cu0.5 Zr)x/2 O19(x=O,1,2,3).采用原位聚合法制备了BaFe9(Ni0.5 Cu0.5 Zr)3/2 O19/聚苯胺复合材料.用X射线衍射分析技术(XRD)进行了物相与结构分析,在2-18GHz频率范围内用矢量网络分析仪测量了样品的复电磁参数,分析它们的吸波性能.实验表明:用石蜡作为粘合剂,BaFe9(Ni0.5 Cu0.5 Zr)3/2 O19/聚苯胺复合材料在BaFe9(Ni0.5 Cu0.5Zr)3/2 O19与聚苯胺质量比为1:1,厚度为2mm时微波吸收能力最强,在11.8GHz时反射率为-21.7dB.在保持最大反射率基本不变的情况下,可以通过改变吸波材料的厚度,调节其共振频率.
