| 摘 要： | 用石蜡分别与多壁碳纳米管及大内径薄多壁碳纳米管按不同的质量比混合,制得了复合吸波材料.采用同轴法测量了复合材料在2~18 GHz范围内的复介电常数和复磁导率,并计算了材料对微波的反射率,分析了其吸波性能.结果表明:碳纳米管复合材料在2~18 GHz范围具有吸波性能.其中质量分数为15％的多壁碳纳米管的最大吸收峰在10.4 GHz,其值为-21.7 dB,质量分数为15％的大内径薄壁多壁碳纳米管的最大吸收峰在11.2 GHz,值为-17.6 dB.

| Abstract: | Multi-walled carbon nanotubes and large inner diameter-thin walled carbon nanotubes were respectively combined with paraffin wax in different mass ratio to prepare microwave absorption composites.The complex permittivity and permeability of the composites were measured,and the reflectivity of electromagnetic waves was calculated.The results show that maximum absorption of the multi-walled carbon nanotubes is about -21.7 dB at 10.4 GHz,and that of the Large Inner Diameter-thin walled Carbon Nanotubes is -17.6 dB at 11.2 GHz. |
