Study on the Microwave Permeability of the CNT Complex in 2-18GHz

The frequency spectrum of the permeability of the single-walled carbon nanotubes (SWCNT)-paraffin complex is studied in 2-18GHz, which is very important for the absorption performance of materials. The microwave absorption materials are required by strong absorption performance, wide frequency band, thin thickness, and good environmental stability. Traditional microwave absorption materials could not well fulfill above requirements. By the measurement and acquisition of the permeability paramet of SWCNT-paraffin complex in 2-18GHz and the Origin software under different conditions, the influence of the concentration and frequency of the complex on the permeability of the carbon nanotubes is analyzed in this article.
