摘要

本研究探讨了用磁铁矿 Fe3O4 纳米粒子制造复合材料作为屏蔽电磁辐射的方法。研究了不同重量百分比的 Fe3O4 纳米粒子对微波吸收的影响。使用 XRD、SEM 和标量网络分析仪对样品进行了表征。结果表明，Fe3O4 纳米粒子的平均尺寸为 175 nm。厚度为 4 毫米、在 1 立方厘米硅橡胶中浓度为 1.5 克的纳米复合材料样品的反射损耗水平最高（-23 dB）。

COMPOSITE MATERIALS BASED ON NANOSIZED FERRITE FOR MICROWAVE APPLICATIONS

The fabrication of composites with magnetite Fe3O4 nanoparticles was investigated in this research as a method of shielding electromagnetic radiation. The effects were studied of various weight percentages of Fe3O4 nanoparticles on the microwave absorption. XRD, SEM, and a scalar network analyzer were used to characterize the sample. The results showed that the Fe3O4 nanoparticles had an average size of 175 nm. The nanocomposite sample with a thickness of 4 mm and a concentration of 1.5 g in 1 cm3 of silicon rubber had the highest level of reflection loss (-23 dB).
