摘　　要：采用化学镀法在石墨基体表面沉积出Ni-Fe-P合金催化剂,通过SEM、XRD、EDX对合金催化剂进行分析表征。通过CVD法,以热处理后的Ni-Fe-P合金作为催化剂,噻吩为助催化剂,乙炔为碳源,反应温度为650℃条件下成功制备出螺旋碳纤维。研究发现所得产物全部为尺寸、形貌规整的双螺旋碳纤维,纤维长度达到毫米级,螺旋直径及单根纤维直径分别为2～3μm、0.5～0.8μm。The Ni-Fe-P alloy catalysts were deposited on the graphite matrix using electroless plating method,the catalysts were also characterized and analyzed by scanning electron microscopy, X-ray diffraction, energy dispersiveX-ray. Using the heat treated Ni-Fe-P alloy as catalyst, thiophene as impurity, acetylene as the carbon source,the carbon micro-coils were successfully prepared by chemical vapor deposition method under the reaction temperatureat 650℃. The study found that the resulting products are almost a regular dimension, morphology of the double helixcarbon fibers, the length of the fiber is millimeter, the helix diameter and the single fiber diameter are 2 to 3 μm,0. 5to 0. 8 μm.
