| 英文摘要 | Dielectric nanocomposites with an enhanced energy density are highly desired in modern electronic and electrical power systems. In this paper, we developed a new flexible dielectric nanocomposite thin film using Y-doped barium strontium titanate (Y:BST) nanoparticles as fillers and polyvinylidene fluoride (PVDF) as a polymer matrix. The nanocomposites exhibited a high energy density of 11.07 J/cm3 at 4300 kV/cm with a low filler content. Through the analysis of defect chemistry with X-ray photoelectron spectroscopy (XPS), the dopant Y3+ occupies A-site of the perovskite structure, which is associated with the generation of Ba&Sr vacancies and oxygen vacancies for charge compensation. As a result, TiO62- octahedron distortion occurs, which is responsible for the enhanced dielectric permittivity. Meanwhile, the dielectric loss maintains a low level and the breakdown strength increases at a low filler loading, resulting in improved energy density. |
