Bismuth strontium titanate-based lead-free relaxor ferroelectric film, preparation method and application
According to the bismuth strontium titanate-based lead-free relaxor ferroelectric film, the preparation method and the application thereof, a barium titanate ferroelectric material is introduced into a bismuth strontium titanate base through a sol-gel method, the dielectric constant and the density of the material are improved, then the energy storage performance of the material is improved, on the basis, the breakdown field strength of the material is improved by combining introduction of the Mn element, and therefore the energy storage performance of the material is improved. The P-E curve of the material becomes slender, the energy storage density and energy storage efficiency of the bismuth strontium titanate-based lead-free relaxor ferroelectric film are greatly improved, and high energy storage density and high energy storage efficiency can be kept in different electric fields.
本发明提供一种钛酸锶铋基无铅弛豫铁电薄膜、制备方法及其应用，通过溶胶‑凝胶法在钛酸锶铋基中引入钛酸钡铁电材料，提高材料的介电常数以及致密度，进而提高材料的储能性能，在此基础上，结合引入Mn元素，使得材料的击穿场强提升，使材料的P‑E曲线变得纤细，大大提高了钛酸锶铋基无铅弛豫铁电薄膜的储能密度和储能效率，在不同电场下都能保持高储能密度和高储能效率。
