摘　　要：在250，280，310℃的低温条件下，以乙炔为碳源，纳米铜粒子作为催化剂，用CVD法制备螺旋纳米炭纤维．并对其表面形貌、元素组成和分布、晶体结构进行了研究。研究表明：在低能耗条件下，制备的螺旋状纳米炭纤维直径在100～300nm．且产量丰富，可望实现工业化推广。螺旋状纳米炭纤维的C的原子数分数在85％以上，用XRD表征螺旋纳米炭纤维表明．螺旋纳米炭纤维是非晶体的，不是石墨态的，结构不完整。The helical carbon nanofibers were prepared by CVD method in low temperatures such as 250℃, 280 ℃, and 310℃, respectively, with acetylene as carbon source and copper nanoparticles as catalyst. The surface morphology, composition and distribution of element, and crystal structure of the helical carbon nanofibers were investigated. The result shows that under the condition of low energy consumption, the diameters of helical carbon nanofibers are between 100-300 nm, and the output is rich, helical carbon nanofibers is expected to realize industrialization. Carbon atomic percentage in helical carbon nanofibers is more than 85%. XRD results showed that the helical carbon nanofibers exhibit amorphous structure.
