采用静电纺丝技术,通过改进实验装置,在最佳的纺丝条件下制备了[Ni(CH3C00)2+PVP]-[Zn(CH3C00)2+PVP]-FTi(OC4H9)4+CH3C00H+PVP]前驱体复合电缆,在600℃下将其进行热处理,制备出了NiO-ZnTiO3-Ti02同轴三层纳米电缆。采用热重一差热(TG-DTA)、X射线衍射(XRD)、傅里叶变换红外光谱(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。对NiO-ZrlTiO3-TiQ同轴三层纳米电缆的形成机制进行了讨论。结果表明,所得产物为NiO-ZnTiO3-TiO2同轴三层纳米电缆。芯层为NiO,直径大约为(42.024±4.405)nm;中间层为ZnTiO3,厚度大约为(55.385±7.681)niTl;壳层为TiO2,厚度大约为(70.747±7.373)nm。

[Ni(CH3COO)2 +PVP]-[Zn(CH3COO)2 +PVP]-[Ti(OC4H9)4 +CH3COOH+PVP]composite cables had been fabricated through modified electrospinning equipment. NiO - ZnTiO3 - TiO2 coaxial trilayered nanocables were obtained by the calcination of the relevant composite cables at 600℃. The samples were characterized by use of thermogravimetric-differential thermal analysis (TG-DTA), X-ray diffraetometry (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Formation mechanism of NiO-ZnTiO3-TiO2coaxial trilayered nanocables was preliminarily proposed. The results show that the samples are NiO-ZnTiO3-TiO2 coaxial trilayered nanocables. The core layer is NiO, and its diameter is about (42. 024±4. 405) nm. The middle layer is ZnTiO3 , and its thickness is about (55. 385±7. 681) nm. The outer layer is TiO2, the thickness is about (70. 747±7. 373) nm.
