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.

Abstract As a type of cellulose ether, cyanoethyl (CEC) is considered to be promising candidate for polymer dielectrics due its sustainable nature and high dielectric constant induced by the cyano groups. However, relatively conduction loss CEC arising from charge motion across degrades properties. In this work, we designed synthesized an all‐organic composite CEC/itaconic anhydride (ITA) improve The matrix was graft functionalized ITA via esterification reaction between groups hydroxyl CEC. Meanwhile, crosslinking structure also established in generation diester. Significantly improved ( ε r ), elevated breakdown strength E b restrained (tan δ ) decreased conductivity σ were observed composites compared with unmodified increased 17 pure 32 CEC/ITA at 1 kHz, soared 145 MV m −1 226 composite. tan reduced 0.24 about 0.05 100 Hz. This should attributed molecule trapping centers electron affinity formation crosslinked networks as well hydrogen bonding, which impeded electric conduction. It provided additional advantages better properties than temperatures, may offer inspiration design preparation bio‐based temperatures. © 2024 Society Chemical Industry.
