在Ni0.5Zn0.5Nd0.02Fe1.98O4纳米粒子表面原位聚合苯胺制备了Ni0.5Zn0.5Nd0.02Fe1.98O4-聚苯胺(PANI)纳米复合材料.铁氧体含量为0％、15％和30％样品的结构、形貌和电磁性能分别采用X射线衍射仪(XRD)、透射电子显微镜(TEM)和HB8510B网络分析仪进行了研究.结果表明,聚苯胺包覆层对Ni0.5Zn0.5Nd0.02Fe1.98O4的结晶度有一定影响.在X波段(8.2～12.4GHz),复介电常数的实部随铁氧体含量的增加而减小,虚部随铁氧体含量的增加而增大.复磁导率的实部和虚部都随铁氧体含量的增加而增大.

Ni0.5Zn0.5Nd0.02Fe1.98O4-polyaniline(PANI) nanocomposites were synthesized by in-situ polymerization of aniline in the presence of Ni0.5Zn0.5Nd0.02Fe1.98O4 nanoparticles.The structure,morphology and electromagnetic properties of the products with 0％,15％ and 30％ (mass fraction) of Ni0.5Zn0.5Nd0.02Fe1.98O4 ferrites were characterized by X-ray diffraction(XRD),transmission electron microscope (TEM) and HB8510B network analyzer.The results indicate that the polyaniline coating layer has an effect on the crystallinity of Ni0.5Zn0.5Nd0.02Fe1.98O4 ferrite.The real and imaginary values of complex permittivity for the Ni0.5Zn0.5Nd0.02Fe1.98O4-PANI nanocomposites decrease and increase with the increase of ferrite content in X-band (8.2—12.4 GHz) frequency range,respectively.Both the real and imaginary values of complex permeability increase as the ferrite percentage increases in the Ni0.5 Zn0.5 Nd0.02Fe1.98O4-PANI nanocomposites.
