摘要

本研究探讨了PTFE／Fe2O3／OPEFB复合材料在X波段的微波衰减和屏蔽性能。使用粉末干混合技术将Fe2O3纳米颗粒掺入PTFE/OPEFB基体中。使用XRD和FESEM对复合材料进行了表征，并使用VNA评估了其衰减性能。结果表明，Fe2O3纳米颗粒的加入改善了微波衰减和屏蔽性能，含有15wt%Fe2O3的复合材料表现出16.02dB的最高衰减。通过FESEM分析证实了Fe2O3纳米粒子的均匀分散，XRD分析证实了复合材料中存在Fe2O3纳米粒子。该研究得出结论，PTFE/Fe2O3/OPEFB复合材料在航空航天、电信和电子行业具有电磁干扰屏蔽应用的潜力。

Investigation of microwave attenuation and shielding performance of PTFE/Fe2O3/OPEFB composites at X-band frequency

This study explored the microwave attenuation and shielding properties of PTFE/Fe2O3/OPEFB composites in the X-band frequency range. Fe2O3 nanoparticles were incorporated into the PTFE/OPEFB matrix using a powder-dry mixing technique. The composites were characterized using XRD and FESEM, and attenuation performance was evaluated using a VNA. The results indicated that the addition of Fe2O3 nanoparticles improved microwave attenuation and shielding properties, with the composite containing 15 wt% Fe2O3 exhibiting the highest attenuation of 16.02 dB. The homogeneous dispersion of Fe2O3 nanoparticles was confirmed through FESEM analysis, and XRD analysis confirmed the presence of Fe2O3 nanoparticles in the composites. The study concludes that PTFE/ Fe2O3/OPEFB composites have potential for electromagnetic interference shielding applications in aerospace, telecommunications, and electronics industries.
