Enhanced Dielectric Performance in PVDF-Based Composites by Introducing a Transition Interface.

ABSTRACT: Polymeric dielectrics have garnered significant interest worldwide due to their excellent comprehensive performance. However, developing polymeric dielectric films with high permittivity (ε_r) and breakdown strength (E_b) and low dielectric loss (tanδ) presents a huge challenge. In this study, amorphous aluminum oxide (Al₂O₃, AO) transition interfaces with nanoscale thickness were constructed between titanium oxide (TiO₂, TO) nanosheets and polyvinylidene fluoride (PVDF) to manufacture composites (PVDF/TO@AO). TO@AO nanosheets showed favorable dispersion in the polymer-based composites. Improved permittivity, suppressed dielectric loss, and enhanced breakdown strength were achieved by introducing AO coating with inte
