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 Nanoscale polar regions, or nanodomains (NDs), are crucial for understanding the domain structure and high susceptibility of relaxors. However, unveiling evolution function NDs during polarization switching at microscopic level is great challenge. The experimental in situ characterization under electric‐field perturbations, computational accurate prediction dipole within a sufficiently large supercell, notoriously tricky tedious. These difficulties hinder full link between micro dynamics macro switching. Herein, real‐time nanoscale observed visualized an exemplary relaxor system Bi 5‐ x La Mg 0.5 Ti 3.5 O 15 . Two fundamentally different pathways dynamic characteristics revealed: one steep, bipolar‐like two degenerate states; another flat, multi‐step process with thermodynamically stable non‐polar mesophase mediating states. determined by distinct Landau energy landscapes that strongly dependent on intrinsic configurations interdomain interactions. This work bridges gap switching, providing guiding principle strategic design optimization
