Abstract

The limited improvement in discharge energy density (U_e) of polyvinylidene fluoride (PVDF) nanocomposites filled with low-dielectric-constant (ε_r) nanosheets has been addressed by using a superspreading layering strategy. The integration of highly aligned boron nitride nanosheets (BNNS) and well-dispersed BaTiO₃@PEG (BT@PEG) nanoparticles into the PVDF matrix results in a significant enhancement, increasing E_b and ε_r by 52% and 64%, respectively, and achieving an U_e of up to 20.12 J cm⁻³.
