“…With proper selection of the polymer matrix the composite can provide chemical inertness and gas tightness [12]. However, CB-filled polymers have relatively low-bulk electrical conductivities, most of which are below 1 S/cm [10][11][12][13][14][15][16][17]. In order to increase the electrical conductivity, polymers with high carbon powder loading (typically > 50 vol%) have been explored [18,19].…”

“…Small quantities of conducting particles can increase the dielectric constant, without exceeding the critical concentration of percolation [9], that is, avoiding high conductivity. If electrical losses become high, heating of the plastic will occur, resulting in melting or even carbonization.…”

We present the results of the measurement of complex dielectric permittivity, in the microwave frequency region, on glass reinforced polybutylene terephthalate (PBT) with blue inorganic pigments. The cavity resonant method had been used in order to measure the shift in the resonant frequency of the cavity, caused by the insertion of a sample, which can be related to the real part of the complex permittivity. Also, the quality factor of the cavity decreases with the insertion of a sample. The changes in the inverse of this quality factor give the imaginary part. In order to predict the dielectric behavior of this composite, we had developed a program of numerical simulation to calculate the complex permittivity of the inclusion. By using some of dielectric mixture laws (Maxwell-Wagner-Sillars, Hanai, Looyenga, inverse and direct Wiener, and Bruggemann), we can predict the dielectric behavior of the composite in a large range of volume fraction of inclusions.
