| 摘要: 采用同轴静电纺丝技术，以硝酸锌、正硅酸乙酯(C8H20O4Si)、无水乙醇、聚乙烯吡咯烷酮(PVP)和N，N-二甲基甲酰胺(DMF)为原料，成功制备出大量的ZnO@SiO2同轴纳米电缆。用TG-DTA，XRD，SEM，TEM，FTIR等分析技术对样品进行了表征。结果表明，得到的ZnO@SiO2同轴纳米电缆的壳层为无定型SiO2，厚度为50 nm，芯轴为晶态ZnO，电缆直径为300~450 nm，长度大于300 μm。探讨了ZnO@SiO2同轴纳米电缆的形成机理。 |

| Abstract: ZnO@SiO2 coaxial nanocables were prepared in lagre scale by coaxial electrospinning using Zn(NO3)2, C8H20O4Si, absolute ethanol, Polyvinylpyrrolidone(PVP) and Dimethylformamide(DMF) as the starting materials. The samples were characterized by TG-DTA, XRD, SEM, TEM and FTIR techniques. The as-prepared coaxial nanocables with a mean outer diameter of 300~450 nm and shell thickness of 50 nm are with a crystalline ZnO core and an amorphous shell of SiO2. The length of ZnO@SiO2 nanocables is greater than 300 μm. |
