High-entropy-component-modified barium titanate-based relaxor ferroelectric material, ferroelectric film with high energy storage characteristic and preparation method of high-entropy-component-modified barium titanate-based relaxor ferroelectric material
The invention relates to a high-entropy component modified barium titanate-based relaxor ferroelectric material, a ferroelectric film with a high energy storage characteristic and a preparation method of the high-entropy component modified barium titanate-based relaxor ferroelectric material. The chemical composition of the high-entropy component modified barium titanate-based relaxor ferroelectric material is (1-x) BaTiO3-xBi (Mg1/5Ni1/5Zn1/5Zr1/5Nb1/5) O3, and x is larger than or equal to 0.08 and smaller than or equal to 0.14. The ferroelectric film with the high energy storage characteristic is composed of a substrate, a lanthanum nickelate conductive layer located in the middle and a barium titanate-based relaxor ferroelectric film located at the top. The preparation method of the ferroelectric film with the high energy storage characteristic comprises the following steps: (1) preparing a lanthanum nickelate conductive layer which grows along a substrate epitaxy; (2) coating the surface of the lanthanum nickelate conductive layer with a barium titanate-based precursor solution for pre-annealing treatment; and (3) carrying out final annealing treatment on the pre-annealed material.
本发明涉及一种高熵组元改性的钛酸钡基驰豫铁电材料、高储能特性的铁电薄膜及其制备方法。所述高熵组元改性的钛酸钡基驰豫铁电材料的化学组成为：(1‑x)BaTiO3‑xBi(Mg1/5Ni1/5Zn1/5Zr1/5Nb1/5)O3，其中，0.08≤x≤0.14。所述高储能特性的铁电薄膜由基底、位于中间的镍酸镧导电层和位于顶部的钛酸钡基驰豫铁电薄膜组成。所述高储能特性的铁电薄膜的制备方法包括：(1)制备沿基底外延生长的镍酸镧导电层；(2)在镍酸镧导电层表面涂覆钛酸钡基前驱液进行预退火处理；(3)对预退火处理完成后的材料进行终退火处理。
