摘要： 采用静电纺丝技术，通过改进实验装置，采用同轴三喷嘴实验装置代替传统的单喷嘴实验装置，在最佳的纺丝条件下制备了[Ni(CH3COO)2+PVP]@[Al(NO3)3+PVP]@[Ti(OC4H9)4+CH3COOH+PVP]前驱体复合电缆，将其进行热处理，制备出了NiO@Al2O3@TiO2同轴三层纳米电缆. 采用差热-热重(TG-DTA)、X射线衍射(XRD)、傅立叶变换红外光谱(FTIR)、扫描电子显微镜(SEM)和透射电子显微镜(TEM)等分析技术对样品进行了表征. 结果表明，所得产物为NiO@Al2O3@TiO2同轴三层纳米电缆. 纳米电缆芯层为NiO，直径大约为137.83±8.85 nm；中间层为Al2O3，厚度大约为215.11±8.66 nm；壳层为TiO2，厚度大约为156.26±16.50 nm. 对NiO@Al2O3@TiO2同轴三层纳米电缆的形成机理进行了讨论.

Abstract: [Ni(CH3COO)2+PVP]@[Al(NO3)3+PVP]@[Ti(OC4H9)4+CH3COOH+PVP] composite cables have been fabricated through modified electrospinning equipment via electrospinning technique. NiO@Al2O3@TiO2 coaxial trilayered nanocables were obtained by calcination of the relevant composite cables. The samples were characterized by thermogravimetric-differential thermal analysis (TG-DTA), X-ray diffractometry (XRD), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), and Transmission electron microscopy (TEM). Results showed that the samples are NiO@Al2O3@TiO2 coaxial trilayered nanocables. The core layer is NiO, and its diameter is ca. 137.83±8.85 nm. The middle layer is Al2O3, and its thickness is ca. 215.11±8.66 nm. The outer layer is TiO2, the thickness is ca. 156.26±16.50 nm. Formation mechanism of NiO@Al2O3@TiO2 coaxial trilayered nanocables was preliminarily proposed.
