• a parallel capacitor. The model is presented in Figure 10. The values of the serial and parallel resistances can be calculated directly from the Cole–Cole diagrams using the equation: To determine the parallel capacitance for the two samples, we extracted relevant information from the frequency plot

• the activation energy were determined, and found to be in good agreement with previously obtained data. The relaxation time was obtained by fitting the spectra of the dielectric loss with the Havriliak–Negami function. Impedance measurements were evaluated using Cole–Cole diagrams and the three

• consistent with a possible electric contact between the coated substrates of the LC cell caused by the reorientation of the nanotubes. The reversibility of the doped system upon removal of the electric field is quite low. Keywords: carbon nanotubes; Cole–Cole diagrams; impedance; liquid crystal; PEDOT:PSS
