▲ Abstract:
Dielectric polymers used in electrical energy storage require a combination of key metrics, including a high dielectric constant (K), low loss and high breakdown strength (Eb), all while being capable of operating at high temperatures. Decades of research into polymer–inorganic composites have achieved only limited success in reaching these goals. Here we introduce high-temperature immiscible blends of two dipolar polymers that, through nanophase separation, self-assemble into three-dimensional all-polymer nanocomposites. The resulting nanostructures induce coiled-chain morphology and large conformation changes, which, combined with relatively low rotational barrier and high dipole moments of both polymers, yield ultrahigh dielectric responses while maintaining a low loss across a wide temperature range. Simultaneously, the nanostructured interfaces act as barriers for mobile charges, markedly reducing conduction losses at high fields and temperatures. The all-polymer three-dimensional nanocomposites with concurrently high K, high Eb and low loss deliver unprecedented discharged energy densities at elevated temperatures. The approach is applicable to other immiscible dipolar blends, demonstrating its universality and tunability. This work addresses the urgent needs in electrical energy storage and provides a new paradigm towards high-energy-density polymer dielectrics over a broad temperature range.
