Abstract
To improve the synergistic effect between dielectric and magnetic loss is a practical and effective way in optimizing electromagnetic wave absorbing materials. The composites of metal particles and carbon ligands derived from metal organic frameworks have gained wide attention. In this study, Co particles and multiwalled carbon nanotubes (CNT) were successfully synthesized covering the surface of silicon carbide (SiC) fibers, and the morphology, interfaces and electromagnetic wave absorption performance were explored. For sample SiC@Co/CNT, the minimum reflection loss value can reach -70.22 dB at 11.21 GHz with the thickness of 2.12 mm. The effective absorbing bandwidth can reach up to 6.03 GHz with the thickness of 1.71 mm, which covers the entire Ku band. It brings more interfaces between Co particles and CNTs as well as SiC fibers and Co/C nanosheets. The interfacial polarization has been hugely enhanced, and the microwave absorbing properties have been improved. This article reports on the impedance matching of magnetic and non-magnetic components and the heterointerface engineering, which can be effective strategy and inspiration to illustrate the relationship between components, structures and functions of electromagnetic wave absorbing materials.
提高介电损耗和磁损耗之间的协同效应是优化电磁波吸收材料的一种实用而有效的方法。由金属有机框架衍生的金属颗粒与碳配体的复合材料受到广泛关注。本研究成功合成了覆盖在碳化硅(SiC)纤维表面的 Co 粒子和多壁碳纳米管(CNT),并对其形貌、界面和电磁波吸收性能进行了探讨。对于厚度为 2.12 mm 的 SiC@Co/CNT 样品,在 11.21 GHz 频率下的最小反射损耗值可达 -70.22 dB。厚度为 1.71 mm 时,有效吸收带宽可达 6.03 GHz,覆盖了整个 Ku 波段。它为 Co 粒子和 CNT 以及 SiC 纤维和 Co/C 纳米片之间带来了更多的界面。界面极化大大增强,微波吸收性能也得到改善。本文报告了磁性和非磁性元件的阻抗匹配以及异界面工程,这对于说明电磁波吸收材料的元件、结构和功能之间的关系是一种有效的策略和启发。
