The results show that the zirconium sol has good spinnability when n: n= 1:3, reaction time is 6h and aging temperature is 15℃. The ZrO_2precursor fibers are made from hydrous zirconia chelated by acetylacetone. The sintercd fibers arecomposed of metastable tetragonal phase and sized about 15μm in diameter. Moreover, there aremany pores inside the fibers, but no cracks.4. ZrO_2/PVP hybrid fibers were prepared by blending the spinnable zirconium sol and 10 wt%PVP solution.
结果表明,当n(ZrOCl_2·8H_2O):n(H_2O_2)=1:3,反应时间6h,陈化温度15℃时可得纺丝性能良好的锆溶胶,ZrO_2前驱体连续纤维的组成主要为经乙酰丙酮配位的ZrO_2水合物,热处理后的ZrO_2纤维的相结构为亚稳四方相,纤维的直径为15μm左右,纤维中存在大量的纳米级气孔,但无明显裂纹。4。
