通过溶胶-凝胶法和静电纺丝技术制备的氧化锆/聚醋酸乙烯酯(PVAc)复合纳米纤维经煅烧合成了直径约200 nm的纳米尺寸氧化锆(ZrO2)纤维。通过扫描电子显微镜（SEM）和原子力显微镜（AFM）研究了纳米纤维的一般形态。通过纳米纤维的 X 射线衍射图样 (XRD) 研究了晶相演化随煅烧温度的变化，结果表明，在 500 ℃ 和 750 ℃ 下煅烧后的样品显示出四方相以及一些痕量的单斜氧化锆的存在。在 1000 摄氏度下煅烧后，在 XRD 图中仅识别出单斜晶相。 FT-IR 光谱进一步证实了纯氧化锆的形成。
Nanometer-sized zirconium oxide (ZrO2) fibers with diameters about 200 nm have been synthesized by calcination of the zirconium oxide/poly(vinyl acetate) (PVAc) composite nanofibres prepared by sol-gel processing and electrospinning technique. The general morphology of the nanofibers has been studied by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The crystalline phase evolution as a function of calcination temperature was studied by X-ray diffraction patterns (XRD) of the nanofibers, which showed that the samples after calcination at 500 degrees C and 750 degrees C showed the presence of tetragonal phase along with some traces of monoclinic zirconium oxide. After calcination at 1000 degrees C, only monoclinic phase was identified in the XRD patterns. The formation of pure zirconium oxide was further confirmed by FT-IR spectra.
