Abstract. The dielectric relaxation characteristics of different concentrations of carbon nanotubes loaded in polyester polymer matrix has been studied as a function of frequency over a wide range (100 Hz–106Hz). The effect of filler loading and frequency dependence on the real and imaginary parts of the impedance was explained by the relaxation process. Spectral curve of impedance was fitted using the Cole-Cole dielectric relaxation function. The calculated relaxation parameters of this model and the distribution function of relaxation times are calculated and presented.
