Carbon nanotubes and carbon nanobelts were obtained via single-needle electrospinning on a basis of water-in-oil (W/O) emulsion technique, respectively. The morphology of electrospun products can be controlled by controlling the temperature of the collector during the electrospinning process. The mechanism of fabricating PAN nanotubes and nanobelts by emulsion electrospinning is discussed in detail. Transmission electron microscopy and scanning electron microscope results show that the carbon nanotubes (the inner diameter of 25-50 nm and the outer diameter of 50-100 nm) have a wall thickness of 10-50 nm, and the width and thickness of the nanobelts range from 100 to 300 nm, and 1 to 5 nm, respectively. A slight difference of bonding configuration of the carbon nanofibers, carbon nanotubes and carbon nanobelts is attributed partly to their different topological structures. The novel method is versatile and could be extended to the fabrication of various types of nanotubes and nanobelts.
分别通过基于油包水（W/O）乳液技术的单针静电纺丝获得了碳纳米管和碳纳米带。通过控制静电纺丝过程中收集器的温度，可以控制电纺产品的形态。详细讨论了乳液静电纺丝制备 PAN 纳米管和纳米带的机理。透射电子显微镜和扫描电子显微镜结果表明，碳纳米管（内径为 25-50nm，外径为 50-100nm）具有 10-50nm 的壁厚，纳米带的宽度和厚度范围分别为 100-300nm 和 1-5nm。碳纳米纤维、碳纳米管和碳纳米带的键合结构略有差异，部分原因在于它们的拓扑结构不同。这种新颖的方法具有通用性，可以扩展到各种类型的纳米管和纳米带的制造。
