Flexible rare earth zirconate high-entropy ceramic fiber membrane as well as preparation and application thereof
The invention provides a zirconium-rare earth ion acetylacetone polymer and preparation thereof, a flexible rare earth zirconate high-entropy ceramic fiber membrane and preparation and application thereof, and relates to the technical field of ceramic fibers. The zirconium-rare earth acetylacetone polymer is of a one-dimensional chain structure and has high spinnability, and when the zirconium-rare earth acetylacetone polymer is used for preparing a rare earth zirconate high-entropy ceramic fiber membrane, it is not needed that excessive spinning auxiliaries are added, so that the flexibility of the fiber membrane is lost during subsequent calcination. Besides, the rare earth elements in the zirconium-rare earth acetylacetone polymer are any five of La, Nd, Sm, Eu, Gd, Dy, Y, Ho, Er, Yb and Lu, the hysteresis diffusion effect brought by the high-entropy effect enables fiber grains to be small, and the flexibility of the fiber membrane is improved.
本发明提供了一种锆‑稀土离子乙酰丙酮聚合物及其制备、柔性稀土锆酸盐高熵陶瓷纤维膜及其制备和应用，涉及陶瓷纤维技术领域。本发明的锆‑稀土乙酰丙酮聚合物为一维链状结构，具有较高的可纺性，用于制备稀土锆酸盐高熵陶瓷纤维膜时，不必加入过量纺丝助剂使得后续煅烧时纤维膜柔性丧失。此外，所述锆‑稀土乙酰丙酮聚合物中的稀土元素为La、Nd、Sm、Eu、Gd、Dy、Y、Ho、Er、Yb和Lu中的任意5种，高熵效应带来的迟滞扩散效应使得纤维晶粒较小，提高了纤维膜的柔性。
