PVDF nanocomposites with aligned boron nitride nanosheets and dispersed BaTiO3@PEG nanoparticles by a superspreading strategy towards high energy density

The limited improvement in discharge energy density (Ue) of polyvinylidene fluoride (PVDF) nanocomposites filled with low-dielectric-constant (ϵr) nanosheets has been addressed by using a superspreading layering strategy. The integration of highly aligned boron nitride nanosheets (BNNS) and well-dis...

Zusammenfassung:The limited improvement in discharge energy density (Ue) of polyvinylidene fluoride (PVDF) nanocomposites filled with low-dielectric-constant (ϵr) 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 Eb and ϵr by 52% and 64%, respectively, and achieving an Ue of up to 20.12 J cm−3.
