Different polymeric composite samples from Poly(acrylonitrile-butadiene-styrene) (ABS) Terpolymer and Tetrabutylammonium Tetrafluoroborate were prepared and their dielectric spectra were measured in the frequency range from 0.2 Hz to 100 kHz and in temperature interval from room temperature to 463 K. AC conductivity of these composites is found to be frequency and temperature dependent, and it generally follows the exponential law, σac ωn. The values of n were calculated at all temperatures for all samples. Dielectric relaxation has been investigated and it was found that all samples are characterized by high dielectric constant values at very low frequency and high temperature. The results are discussed in terms of interfacial Maxwell-Wagner-Sillars (MWS) polarization and space-charge polarization.
