摘　　要：同轴静电纺丝技术制备的核-壳复合结构纳米纤维已取得了显著成果,在众多领域都具有较大的应用价值。通过对传统静电纺丝和同轴静电纺丝进行比较,分析了同轴静电纺丝的特点,并指出复合泰勒锥体和喷射流的稳定性直接影响着复合纳米纤维的形貌。重点讨论了纺丝过程中诸如黏度、浓度、电纺性、溶剂挥发性等溶液参数和流速、电压等工艺参数对核-壳结构纳米纤维形貌的影响作用,并探讨了流速对纤维成丝性的影响。最后归纳了核-壳结构纳米纤维在能源、组织工程、传感器等领域的优势和潜在应用。The core-shell compound nanofibers prepared by the coaxial electrospinning achieve remarkable achievements, and have good application values in many fields. By comparing the diffe- rence between the ordinary electrospinning and coaxial electrospinning, the characteristics of the coaxial electrospinning are analyzed, and the morphology of the compound nanofibers directly affected by the composite Taylor cone and stability of the jet stream is indicated. The effects of so- lution parameters such as viscosity, density, spinnability, solvent volatility and process parameters such as flow rate and voltage on the morphology of the core-shell compound nanofihers are emphatically discussed, and the effect of the flow rate on the formation of core-shell structure is also discussed. Finally, the advantages and potential applications of the core-shell compound nanofibers in the fields such as energy, tissue engineering and sensors are concluded.
