Based on an equivalent resistance-capacitance network, the complex conductivity and the relative complex permittivity of single wall carbon nanotubes （SWNTs）/polymer composite are theoretically investigated in the frequency range of 0.30-18 GHz using the logarithmic rule. Both the real and imaginary parts of the permittivities of SWNTs and polymer are considered in detail. The calculated complex permittivity spectra of SWNTs/poly（ethyl methacrylate） composite films are in good agreement with the available experimental data. The influences o...

基于一个相等的抵抗电容网络，复杂传导性和单个墙碳 nanotubes (SWNT ) 的相对复杂介电常数 /polymer 合成理论上用对数的规则在 0.30 18 GHz 的频率范围被调查。两个都， SWNT 和聚合物的介电常数的真实、想象的部分详细被考虑。合成电影在对可得到的试验性的数据的好同意的 SWNTs/poly (乙醇 methacrylate ) 的计算复杂介电常数系列。复杂传导性和绝缘的损失正切上的 SWNT 集中的影响合成在微波频率范围被介绍。在微波电导率和频率之间的一种线性关系被发现。
