Summary Hybrid composites consisted of an epoxy resin and BaTiO 3 as well as ZnO particles were prepared and studied. Polymer composites with ferro‐ and/or piezo‐electric particles are expected to exhibit functional behaviour due to the varying polarization of the fillers. The BaTiO 3 content was kept constant in all studied composites, while ZnO content varied from 0 to 50 particles per hundred resin per weight. Thermal properties of the systems were examined by means of Thermogravimetric/Differential Thermal Analysis technique. Decomposition temperature for all systems was found to lie in the range 385–395 °C, while residual weight for hybrids was significantly higher compared to epoxy resin. Dielectric response of the tested systems was determined via Dielectric Relaxation Spectroscopy.
