摘　　要：采用低碳钢基体表面氧乙炔火焰法成功合成了纳米碳纤维，利用扫描电镜、激光拉曼光谱检测手段对其形貌和结构进行了表征。在氧乙炔火焰内焰区，经浓硝酸浸蚀的低碳钢表面沉积合成出中空管状、短而粗的纳米碳纤维：外径100～120nm，内径60-80nm。并初步探讨了其火焰合成的形成环境和生长过程。Carbon nanofibers have been successfully synthesized on low carbon steel using oxygen-acetylene flame, Their morphologies and microstructures have been characterized using scanning electron microscopy and micro-Raman spectroscopy respectively. Carbon nanofibers deposited on low-carbon steel surface within inner flame zone were hollow, short and thick with an outer diameter of 100 - 120nm and an inner diameter of 60 - 80nm, and low-carbon steel surface was pretreated by dipping in concentrated nitric acid solution. The growth surroundings and processing of carbon nanofibors are preliminary discussed.
