Abstract: Composites based on high-pressure polyethylene reinforced with a bentonite filler were developed and analyzed. The defined significant frequency-dependent dispersion of the dielectric parameters is attributed to the migration of intrinsic point defects, such as vacancies, interstitial atoms, and structural defects within the filler sublattice. These findings highlight the critical role of both filler content and defect dynamics in determining the electrical performance of HPPE-based composites. The temperature dependence of the permittivity ε of the composites indicates that permittivity exhibits a steady increase with rising temperature, indicating enhanced polarization mechanisms at elevated temperatures. Dielectric loss tangent behavior is characterized by a more complex, non-monotonic trend. The observed distinct maxima suggested the presence of thermally activated processes, and peaks are likely associated with changes in the structural parameters of the interphase boundary layer, which may arise due to phase transitions occurring within the filler crystals.
