Study on the Carbon Nanotube/Carbonyl Iron Composites

摘要: 以羰基铁粉和碳纳米管作为主吸收剂，通过共混的方式制备出复合吸收剂，并对制备产物的电磁特性和反射率进行了表征。实验结果证明：通过共混的方式制备的吸收剂具备介电和磁损耗双复损耗特性，通过对复合吸收剂的反射率的仿真模拟可以发现，复合粉体的综合吸波性能优于单一吸收剂的吸波性能。本文同时对双复吸波材料的微波吸收机理进行了分析。

Abstract: The composite absorber was prepared by mixing carbonyl iron power and carbon nanotube as the main absorbent. The electromagnetic properties and reflectivity of the samples were characterized. The experimental results show that the composite absorber has the dual loss characteristics of dielectric and magnetic loss. Through the stimulate of the reflectivity of the samples, it can be found that the comprehensive microwave absorbing performance of the composite is better than that of the single absorber. Meanwhile, the microwave absorbing mechanism of composite is analyzed.
