Abstract Polymer-based dielectrics are widely employed in electrostatic energy storage capacitors serving as pulse power supply owing to their lightweight nature and rapid charge-discharge capability. However, their intrinsically low dielectric constant severely limits energy storage density. Although high-dielectric-constant nanofillers are commonly incorporated to enhance permittivity, organic-inorganic interfacial incompatibility often induces particle agglomeration and structural defects.

Abstract Dielectric elastomers are soft electroactive polymers capable of large-strain actuation with the moniker artificial muscle. However, current dielectric elastomers exhibit limited operational stability when operated at strain and energy density in the neighborhood of natural muscles, due to mechanical fatigue or electrical breakdown.
