| 摘 要： | 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(CH3COO)2＋PVP]@SnCl4＋PVP]@Zn(CH3COO)2＋PVP]@Ti(OC4H9)4＋CH3COOH＋PVP]前驱体复合电缆, 将其进行热处理, 制备出NiO@ SnO2@Zn2TiO4@TiO2同轴四层纳米电缆. 采用热重-差热(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, 所得产物为同轴四层纳米电缆, 芯层为NiO, 直径为35～55 nm|第二层为SnO2, 厚度为30～50 nm|第三层为Zn2TiO4, 厚度为25～40 nm|壳层为TiO2, 厚度为40～90 nm. 对同轴四层纳米电缆的形成机理进行了探讨.
