采用静电纺丝技术，从含有聚乙烯吡咯烷酮（PVP）和合适的钇水前体的醇溶液中制备均匀的I-D无机-有机复合纳米纤维。和锆离子。在仔细预选的时间-温度曲线下烧制和烧结后，获得了氧化钇稳定的氧化锆纳米纤维，其保留了在初纺组合物中观察到的原始形态特征。 X 射线衍射用于鉴定最终产品的结晶命运。采用拉曼光谱和扫描电子显微镜（SEM）等分析工具来阐明陶瓷相形成的途径以及纺丝和加工纤维形态特征的系统演化。可以制造出几毫米长、均匀、高相纯度的 YSZ 纳米纤维。 (C) 2005 Elsevier B.V. 保留所有权利。
The technique of electrospinning was employed to fabricate uniform I-D inorganic-organic composite nanofibers from alcoholic solutions containing polyvinyl pyrrolidone (PVP) and suitable aqueous precursors of yttrium. and zirconium ions. Upon firing and sintering under carefully pre-selected time-temperature profiles, yttria-stabilized zirconia nanofibers retaining the original morphological features observed in the as-spun composition were obtained. X-ray diffraction was used to identify the crystalline fate of the final product. Analytical tools such as Raman spectroscopy and scanning electron microscopy (SEM) were employed to elucidate the pathway of ceramic phase formation and the systematic evolution of morphological features in the spun and the processed fibers. Several millimeters long, uniform YSZ nanofibers of high phase purity could be fabricated. (C) 2005 Elsevier B.V. All rights reserved.
