1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Polymer film capacitors are indispensable for energy storage and power conversion, yet their energy density and efficiency deteriorate rapidly at elevated temperatures. At temperatures relevant to wide-bandgap semiconductor electronics (>150°C), heat-resistant polymer films must be heavily derated to avoid premature aging due to intensive hot-carrier injection. Inspired by multilayered barrier structures in nature, we developed a scalable roll-to-roll self-assembled organic-inorganic nanolaminate coating that significantly enhances the high-temperature dielectric performance of polymer films. The nanolaminate architecture introduces dual confinement mechanisms: nanoconfinement of the polymer binder suppresses chain motion and enhances thermal stability, while anisotropic carrier relaxation within two-dimensional nanoclay nanosheets impedes through-plane hot-carrier transport. Together, these effects synergistically establish an interface-rectification mechanism that promotes in-plane energy dissipation and suppresses carrier injection at electrode-polymer interfaces. At 150°C, the coating significantly reduces the pre-breakdown conduction current of polyetherimide (PEI), increases the breakdown strength from 450 to 501 MV/m, and improves the discharged energy density at 95% efficiency by 105%. Furthermore, roll-to-roll-coated PEI capacitors exhibit a 45-fold lifetime enhancement at 150°C and 180 MV/m-a design field previously sustained only by BOPP below 60°C. This work provides a scalable and technology-ready strategy for high-temperature, high-density polymer capacitive energy storage.
