Abstract
Flexible Nd-doped BaTiO3@Al2O3/polyvinylidene fluoride (PVDF) composites have been successfully developed. With the reaction temperature of 70∘C, Nd-doped BaTiO3@Al2O3 particles display uniform core–shell structures and disperse well in the PVDF matrix. Due to the benign dielectric properties of Nd-doped BaTiO3 and great suppression of the Al2O3 coating on the leakage current and dielectric loss, the Nd-doped BaTiO3@Al2O3/PVDF composites with different Nd-doped BaTiO3@Al2O3 filling ratios (0–4[Formula: see text]vol.%) exhibit relatively good dielectric and energy storage performance. Among them, the maximum discharged energy density of 8.6[Formula: see text]J/cm3 was achieved in the composite with 1[Formula: see text]vol.% Nd-doped BaTiO3@Al2O3 loading.
