Abstract High dielectric constant ( ε ), thermal conductivity (TC), and breakdown strength E b ) along with low loss flexible polymeric nanocomposites display multifunctional applications. In this work, to synergistically bolster the TC while restraining leakage current in percolating flaky copper f ‐Cu)/poly(vinylidene fluoride) (PVDF), presenting a giant , core@shell structured ‐Cu@MgO (magnesium oxide) nanosheets were first created via chemical precipitation method, then incorporated into host PVDF explore MgO shell’ impact on properties of resulting nanocomposites. The introduced interlayer strengthens interfacial interactions significantly mitigates mismatch both between ‐Cu PVDF, elevated ‐Cu@MgO/PVDF comparison pristine ‐Cu/PVDF. Furthermore, insulating introduces deep traps inhibits long‐distance migration electrons, leading remarkably suppressed loss. More importantly, can be optimized by tuning thickness. fitting results Havriliak‐Negami equation theoretically support shell's suppression effect charge reveal underlying polarization mechanism developed currently high but loss, present promising applications electrical power systems.
