以无水乙醇为溶剂，聚乙烯吡咯烷酮和正硅酸乙酯为原料，通过溶胶-凝胶法制备纺丝前驱体，然后利用静电纺丝技术得到电纺纤维，再经煅烧处理后得到外径150 nm左右的二氧化硅纳米管。通过场发射扫描电子显微镜（FE-SEM）和透射电子显微镜（TEM）研究电纺纤维和二氧化硅纳米管的形貌，利用傅里叶转换红外光谱（FT-IR）和X-射线多晶粉末衍射仪（XRD）证明二氧化硅纳米管的形成。结果显示：当纺丝参数分别为电压10 kV、流速1．5mL/h、接收距离14cm，原料配方为：聚乙烯吡咯烷酮1．5g、无水乙醇16mL、正硅酸乙酯3．2mL时，获得的电纺纤维和二氧化硅纳米管均具有良好的形貌。

T he electrospinning precursor is obtained by selecting absolute ethyl alcohol as the solvent and polyvinylpyrrolidone (PVP) and ethyl orthosilicate (TEOS) as the raw materials through sol-gel method .Then the electrospun fibers are acquired by electrospinning technique and SiO 2 nanotube with the outer diameter of about 150 nm was gained by calcination treatment .The morphology of electrospun fibers and SiO2 nanotube are studied through field emission scanning electron microscopy (FE-SEM ) and trans-mission electron microscopy (TEM) .The formation of SiO2 nanotube is proved through Fourier transform infrared spectroscopy (FT-IR) and X-ray powder diffraction (XRD) .The results indicat that the electro-spun fibers and SiO2 nanotube had good morphology when the electrospinning parameters were as follows :voltage 10 kV ,flow rate 1 .5 mL/h ,the receiving distance 14 cm and when the raw material ratio was as follows :PVP 1 .5 g ,absolute ethyl alcohol 16 mL ,TEOS 3 .2 mL .
