Preparation method of ligand modified zirconium oxide sol and zirconium oxide polycrystalline fiber
The invention relates to a preparation method of ligand modified zirconium oxide sol and zirconium oxide polycrystalline fiber. The preparation method comprises the following steps: dissolving zirconium oxychloride, an organic ligand, an alkaline zirconium source, yttrium salt and a spinning aid in a certain proportion in an aqueous solution to prepare ligand modified zirconium oxide sol; performing electrostatic spinning on the ligand modified zirconium oxide sol to obtain a zirconium oxide precursor fiber; and performing heat treatment on the zirconium oxide precursor fiber to obtain the zirconium oxide polycrystalline fiber. The obtained sol is stable for a long time and good in spinnability, the precursor fiber is high in solid content and insensitive to environmental humidity, the diameter of the obtained polycrystalline zirconia fiber is 0.2-1 micron, the tetragonal phase or cubic phase crystal phase is kept stable at the temperature of 1400 DEG C, and the fiber morphology is complete.
本发明涉及一种配体修饰的氧化锆溶胶和氧化锆多晶纤维的制备方法。制备方法包括将氧氯化锆，有机配体，碱性锆源，钇盐和助纺剂按照一定的比例，在水溶液中溶解，制得配体修饰的氧化锆溶胶；将配体修饰的氧化锆溶胶通过静电纺丝法获得氧化锆前驱体纤维；将氧化锆前驱体纤维通过热处理制得氧化锆多晶纤维。所得溶胶长期稳定，可纺性好，前驱体纤维固含量高，对环境湿度不敏感，所得多晶氧化锆纤维直径为0.2~1μm，在1400℃保持四方相或立方相晶相稳定且纤维形貌完整。
