Abstract


In this article, we studied the microwave permittivity of the complex of the single-walled carbon nanotubes and paraffin in 2-18GHz. In the range, the dielectric loss of single-walled carbon nanotubes are higher, and the real part and the imaginary part of the dielectric constant decrease with the increase of frequency, and the dielectric constant possesses the property of dispersion frequency response. The ??, ?? and tanδ of the complex of the single-walled carbon nanotubes and paraffin increase with the increase of the content of carbon tubes, and it presents good second-order function relationship with the volume fraction of carbon in certain range. The polarization dispersion dielectric response is the main reason that the single-walled nanotubes absorbs and wastes microwaves.
