Broadband dielectric spectroscopy (10−1 to 106 Hz) in combination with TSDC were employed to study the relaxations and the conductivity phenomena in polyamide 6/CaCO3 composites loaded with different contents and particle sizes of treated and untreated CaCO3. In addition to the primary α-relaxation associated with the glass transition, significant interfacial relaxation and ionic conduction processes have been revealed. The temperature dependence of the relaxation rates of α-relaxation and Maxwell–Wagner–Siller-process as well as that of the hopping rate of the conduction mechanism were found to follow the Vogel–Fulcher–Tammann-model. This may support the idea that the three mechanisms are not completely independent. The modification of the filler does not add any effect on the resistivity values.
