CuFe₂O₄ is synthesized by the co-precipitation method, and the hydrothermal method was used to prepare RGO (4, 8 and 12 wt.% reduced graphene oxide)/CuFe₂O₄ nanocomposites. The lattice parameter value of copper ferrite either in composite or in pure form was the same. Average grain size is reduced with the RGO concentration from 70 to 30 nm in nanocomposites. Copper ferrite is very well distributed and firmly anchored on the RGO surface. The Raman spectroscopy confirmed the formation of RGO. Dielectric constant (έ) and ac conductivity values were high and dielectric tangent loss values were low for 8 and 12% RGO/copper ferrite in the measurable frequency range. The highest value of έ is obtained in the 12% RGO/copper ferrite nanocomposite sample and dielectric loss tangent value in the 8% RGO/copper ferrite nanocomposite sample. The experimental impedance data are efficiently simulated by ZView software using an equivalent circuit to extract electrical parameters. It appears that this composite material may find applications in energy storage batteries and microwave absorption devices.

通过共沉淀法合成CuFe ₂ O ₄，并使用水热法制备RGO（4、8和12 wt。％的还原氧化石墨烯）/ CuFe ₂ O ₄纳米复合材料。复合形式或纯形式的铁氧体铜的晶格参数值均相同。在纳米复合材料中，随着RGO浓度从70纳米降低到30纳米，平均晶粒尺寸会减小。铁氧体铜分布非常均匀，并牢固地锚固在RGO表面上。拉曼光谱证实了RGO的形成。在可测量的频率范围内，对于8％和12％的RGO /铜铁氧体，介电常数（έ）和交流电导率值较高，介电正切损耗值较低。在12％RGO /铜铁氧体纳米复合材料样品中获得最高的έ值，而在8％RGO /铜铁氧体纳米复合材料样品中获得的介电损耗正切值。ZView软件使用等效电路有效地模拟了实验阻抗数据，以提取电参数。
