摘要电子设备的发展在方便人类生活的同时也带来了电磁辐射问题,为应对电磁辐射问题,吸波材料成为当下研究的热点。本工作采用水热法、静电纺丝法和高温碳化法制备了Fe₃O₄含量不同的一系列Fe₃O₄-ZIF-67@碳纳米纤维复合材料(Fe₃O₄-ZIF-67@C),复合材料的吸波机理主要包括介电损耗、偶极子极化和界面极化。当四氧化三铁(Fe₃O₄)质量分数为4%时,Fe₃O₄-ZIF-67@C材料的最小反射损耗为-52.15 dB(5.36 GHz处,厚度4.3 mm),最大有效吸收带宽达7.05 GHz(4.63~11.68 GHz,厚度3.5 mm)。因此,该纳米纤维复合材料具有优异的电磁波吸收性能和相对较大的有效吸收带宽,具有良好的应用潜力。

Abstract: The development of electronic devices has brought convenience to people's lives, but also caused the problem of electromagnetic radiation, which makes absorbing materials a hot topic in current research. In this study, a series of Fe₃O₄-ZIF-67@C composite nanofibers differing in Fe₃O₄ content were prepared by hydrothermal method, electrospinning and high-temperature carbonization. The absorption mechanisms of the materials were found to mainly entail dielectric loss, dipole polarization, and interface polarization. When the mass fraction of Fe₃O₄ was 4%, the Fe₃O₄-ZIF-67@C nanofibers exhibited a minimum reflective loss of -52.15 dB at 5.36 GHz and a thickness of 4.3 mm, and a maximum absorption bandwidth of 7.05 GHz (4.63—11.68 GHz) at a thickness of 3.5 mm, demonstrating an excellent electromagnetic wave absorption perfor-mance and a relatively wide effective absorption band, indicating promising application potential.
