PLZT ferroelectric film on flexible yttrium barium copper oxide/hastelloy substrate and preparation method of PLZT ferroelectric film
The invention discloses a PLZT ferroelectric film on a flexible yttrium barium copper oxide/hastelloy substrate and a preparation method of the PLZT ferroelectric film. The chemical formula of the PLZT ferroelectric film is Pb<1-x>La(ZrTi<1-y>)O<3>. The preparation method comprises the following steps: a, weighing lead acetate trihydrate (Pb(CH<3>COO)<2>. 3H<2>O), lanthanum nitrate (La(NO<3>)<3>), tetra-n-butyl titanate (Ti(OC<4>H<9>)<4>) and zirconium n-propoxide (Zr(OC<3>H<7>)<4>) according to a stoichiometric ratio, and dissolving the weighed substances in ethylene glycol monomethyl ether (2-MOE); b, adding deionized water and acetic acid into a mixed solution obtained in the step a to obtain PLZT sol; c, spin-coating a yttrium barium copper oxide/hastelloy substrate having been subjected to heat treatment with the PLZT sol to obtain a wet film; and d, drying the wet film obtained in the step c on a glue drying table, and then carrying out heat treatment to obtain the PLZT ferroelectric film. The PLZT/yttrium barium copper oxide/hastelloy multi-layer ferroelectric film provided by the invention is excellent in dielectric and ferroelectric properties, relatively high in deformability and excellent in application prospects in the field of flexible electronics.
本申请公开了一种柔性钇钡铜氧/哈氏合金衬底上PLZT铁电薄膜及其制备方法，其中PLZT铁电薄膜的化学式为：Pb1‑xLax(ZryTi1‑y)O3，制备方法包括如下步骤：a.将三水合乙酸铅(Pb(CH3COO)2·3H2O)、硝酸镧(La(NO3)3)、钛酸四正丁酯(Ti(OC4H9)4)和正丙醇锆(Zr(OC3H7)4)按照化学计量比称量，溶解于乙二醇甲醚(2‑MOE)之中；b.将步骤a所得的混合液加入去离子水和乙酸，得到PLZT溶胶；c.将所述PLZT溶胶旋涂在热处理后的钇钡铜氧/哈氏合金衬底上，得到湿膜；d.将步骤c所得湿膜置于烘胶台上干燥，随后进行热处理，得到PLZT铁电薄膜。本申请提供的PLZT/钇钡铜氧/哈氏合金多层铁电薄膜介电、铁电性能优异，具有较强的形变能力，在柔性电子领域具有优异的应用前景。
