讨论了采用化学镀的方法将钴铁合金沉积在多壁碳纳米管表面和多壁碳纳米管化学镀前和化学镀后的电磁性能参数,以获得一种轻质、宽频的新型吸波材料。文中列出了场发射扫描电子显微镜,能谱分析和网络矢量分析仪(8722ES)的数据和图标结果。结果发现,铁和钴包覆的MWCNTs在2～18GHz频率范围内具有较好电磁性能。这种材料在6.5GHz电磁波处,其反射率可达-10dB,并且大于-4dB的频宽有5GHz。这种具有优良电磁性能的MWCNTs可以作为吸收剂使用。化学镀后多壁碳纳米管的电磁性能和化学镀前相比有了明显的提高。
The electroless plating method was used to deposit the cobalt-iron alloy on the surface of multi-walled carbon nanotubes and the electromagnetic parameters before and after electroless plating of multi-walled carbon nanotubes to obtain a new type of microwave absorbing material with light weight and broadband. The text lists the field emission scanning electron microscopy, energy spectrum analysis and network vector analyzer (8722ES) data and iconic results. The results show that the iron and cobalt-coated MWCNTs have good electromagnetic performance in the frequency range of 2-18 GHz. This material at 6.5GHz electromagnetic waves, the reflectivity of up to -10dB, and more than -4dB bandwidth of 5GHz. This kind of MWCNTs with excellent electromagnetic properties can be used as absorbent. The electro-chemical plating of multi-walled carbon nanotubes after the electromagnetic properties compared with before plating has been significantly improved.
