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.

Storage Properties

Surface modification of barium titanate particles has been carried out using a wet chemical method. The microstructural and dielectric properties of the ceramics made from surface modified particles were extensively investigated by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and dielectric properties measurements. The breakdown strength increased by 69% and 117% for the Al 2 O 3 and B 2 O 3– SiO 2 modified ceramics, respectively. An energy storage density of up to 3.2 J/cm3 has been obtained. The suppression of grain boundary electron transport and reduction in pore defects lead to the energy storage properties enhancement of the modified ceramics. These results indicated that surface modification of ceramic particles is a promising approach to obtain dielectric ceramics with high energy storage density.
