Polymer dielectric materials are widely used in electrical and electronic systems, there have been increasing demands on their properties at high temperatures. Incorporating inorganic nanoparticles into polymers is an effective approach to improving properties. However, the agglomeration of destabilization organic-inorganic interface temperatures limited development nanocomposites toward large-scale industrial production. In this work, we synthesize metal-organic cage crosslinked by incorporating self-assembled cages with amino reaction sites polyetherimide matrix. The in-situ crosslinking not only achieves a homogeneous distribution components, but also constructs robust interfaces, which avoids interfacial losses conventional improves breakdown strength elevated Ultimately, developed exhibit exceptionally energy densities 7.53 J cm-3 (150 °C) 4.55 (200 charge-discharge efficiency 90%.

Abstract Metallized film capacitors are widely used for their high‐power density, high breakdown strength and prominent machining performance. However, achieving energy density discharge efficiency simultaneously in dielectric polymers remains a significant challenge. To address this issue, the novel random copolymer P(MMA‐VN) is synthesized via copolymerization of 2‐vinyl naphthalene (2‐VN) methyl methacrylate (MMA). This approach takes advantage free volume adjustment capability rigid conjugated rings as side groups, well band modulation effect, to enhance storage Experimental results reveal that incorporation increases thereby improving polarization suppressing relaxation losses. Furthermore, modification levels introduces trap levels, which carrier trapping ability effectively reduce leakage loss probability thermal electrical breakdown. As result, with 5 mol% VN unit exhibits outstanding performance, including an ultrahigh (19.3 J cm − 3 ) remarkable discharging (>89%) at 800 MV m −1 . study proposed strategy reconcile conflict between by regulating level structures.
