论文摘要

使用乙酰乙酸铁的简单混合物与常规的光抗抗 /抗性的简单混合物合成了Fe填充的碳纳米管化学蒸气沉积,并研究了生长温度从550至950°C的生长温度对Fe填充的纳米管的影响。扫描电子显微镜结果表明,随着生长温度从550升至950°C,纳米管的平均直径增加,而其数量密度也下降。高分辨率透射电子显微镜以及能量色散X射线调查表明,纳米管具有多壁结构,所有生长温度都具有部分FE填充。通过X射线衍射模式观察到纳米管的石墨性质。拉曼分析表明,碳纳米管的石墨化程度取决于生长温度。

Fe filled carbon nanotubes were synthesized by atmospheric pressure chemical vapor deposition using a simple mixture of iron acetylacetonate with a conventional photoresist and the effect of growth temperature from 550 to 950 °C on Fe filled nanotubes has been studied. Scanning electron microscopy results show that, as the growth temperature increases from 550 to 950 °C, the average diameter of the nanotubes increases while their number density decreases. High resolution transmission electron microscopy along with energy dispersive X-ray investigation shows that the nanotubes have a multi-walled structure with partial Fe filling for all growth temperatures. The graphitic nature of the nanotubes was observed via X-ray diffraction pattern. Raman analysis demonstrates that the degree of graphitization of the carbon nanotubes depends upon the growth temperature.
