Abstract

Hybridized-carbon-based materials with magnetic metals and oxides have attracted much attention because of their enhanced electromagnetic wave loss. In this study, magnetic particles were coated on the surface of carbon fibers by carbonizing in a nitrogen atmosphere. The morphology, structure, thermolysis, and wave-absorption performance of the carbon fiber/magnetic particle composite were determined. Results show that the -formed magnetic particles (such as FeO, NiFeO, CoFeO, and NiFe) are uniformly dispersed along the carbon-based fibers, which exhibit different wave absorption. The absorption of the carbon fiber/magnetic particle composite can be controlled by adjusting the species and concentration of the magnetic particle coating, which provides a new and effective way of endowing the magnetic-particle-coated carbon fibers with good microwave absorption properties.

摘要

具有磁性金属和氧化物的杂化碳基材料因其增强的电磁波损耗而备受关注。在本研究中，通过在氮气气氛中碳化，将磁性颗粒包覆在碳纤维表面。测定了碳纤维/磁性颗粒复合材料的形貌、结构、热分解和吸波性能。结果表明，形成的磁性颗粒（如FeO、NiFeO、CoFeO和NiFe）沿碳基纤维均匀分散，呈现出不同的吸波性能。通过调节磁性颗粒包覆的种类和浓度，可以控制碳纤维/磁性颗粒复合材料的吸收，这为赋予包覆磁性颗粒的碳纤维良好的微波吸收性能提供了一种新的有效方法。
