摘要

聚偏二氟乙烯（PVDF）纳米复合材料填充了低介电常数（εr）纳米片，但其放电能量密度（Ue）的提高有限。将高度排列的氮化硼纳米片 (BNNS) 和分散良好的 BaTiO3@PEG (BT@PEG) 纳米粒子整合到 PVDF 基体中可显著提高 Eb 和 εr 值，分别提高 52% 和 64%，Ue 值高达 20.12 J/cm³。

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 (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.
