PVDF nanocomposites with aligned boron nitride nanosheets and dispersed BaTiO 3 @PEG nanoparticles by a superspreading strategy towards high energy density

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