Superfine barium strontium titanate nanofiber-based flexible film and preparation method thereof
The invention discloses a superfine barium strontium titanate nanofiber-based flexible film and a preparation method thereof. The preparation method includes the following steps: S1, taking a high polymer material and a solvent and mixing evenly to form a high polymer solution, adding a barium strontium titanate precursor material into the high polymer solution and mixing evenly to form a spinning solution, wherein the mass fraction of the high polymer solution is 2%-30%, and the barium strontium titanate precursor material includes a barium source, a strontium source and a titanium source; in the spinning solution, the mass ratio of the barium strontium titanate precursor material to the high polymer solution is (0.1-10):1; S2, performing solution jet spinning on the spinning solution to obtain barium strontium titanate precursor composite fibers; and S3, calcining the barium strontium titanate precursor composite fibers at the temperature of 700-1100 DEG C. The superfine barium strontium titanate nanofiber-based flexible film produced by adopting a solution jet spinning technology is of a polycrystalline structure, is good in flexibility, simple in process and simple in equipment, can be produced in a macro-scale manner, and has a very wide application prospect in the fields of capacitors, piezoelectricity and the like.
本发明公开了一种超细钛酸锶钡纳米纤维基柔性薄膜及其制备方法，该制备方法包括以下步骤：S1、取高分子材料和溶剂，混匀形成高分子溶液，在高分子溶液中加入钛酸锶钡前驱体材料，混匀形成纺丝液，高分子溶液的质量分数为2％～30％，钛酸锶钡前驱体材料包括钡源、锶源和钛源；纺丝液中，钛酸锶钡前驱体材料：高分子溶液的质量比为(0.1～10)：1；S2、对纺丝液进行溶液喷射纺丝，得到钛酸锶钡前驱体复合纤维；S3、将钛酸锶钡前驱体复合纤维在700～1100℃进行煅烧。本发明采用溶液喷射纺丝技术生产的超细钛酸锶钡纳米纤维基柔性薄膜呈多晶结构，柔性好，工艺简单，设备简易，可宏量化生产，在电容器、压电等领域有很广大的应用前景。
