Photocuring perovskite film and preparation method thereof
The invention provides a photocuring perovskite film and a preparation method thereof, and belongs to the technical field of ceramic material additive manufacturing. The method comprises the following steps: (1) mixing perovskite raw material powder and a surface modifier to obtain perovskite fine powder; (2) mixing the perovskite fine powder and photosensitive resin to obtain perovskite film slurry; and (3) sequentially carrying out 3D printing, degreasing and calcining on the perovskite film slurry to obtain the photocuring perovskite film. According to the preparation method, the surface of the perovskite film raw material powder is modified, so that the surface of the perovskite film raw material powder is coated with a layer of macromolecular modifier, and the dispersity and the stability of the perovskite film raw material powder in the photosensitive resin can be improved through the modification means; the solid phase content of the perovskite powder in the slurry and the quality of a perovskite film are improved; the densification temperature of the membrane is reduced; and the gas permeation flux of the membrane is improved.
本发明提供一种光固化钙钛矿膜及其制备方法，属于陶瓷材料增材制造技术领域。包含下列步骤：(1)将钙钛矿原料粉体和表面改性剂混合得到钙钛矿细粉；(2)将钙钛矿细粉和光敏树脂混合得到钙钛矿膜浆料；(3)将钙钛矿膜浆料顺次进行3D打印、脱脂和煅烧即得所述光固化钙钛矿膜。本发明通过对钙钛矿膜原料粉体表面进行了修饰，使其表面包覆了一层高分子改性剂，通过这种改性手段可以提高钙钛矿膜原料粉体在光敏树脂中的分散性和稳定性；提高浆料内钙钛矿粉体的固相含量以及钙钛矿膜的质量；降低膜的致密化温度以及提高膜的气体渗透通量。
