摘要:

HiPco单壁碳纳米管在H2SO4和HNO3的氧化作用过程中的演变的研究结果。选择所用的工艺条件以避免对纳米管结构的任何显著损害。的类型和水平的功能化,接枝功能的纳米管的表面上的位置和样品的形态特征的变化进行了检查,通过使用广泛的和互补的分析技术。我们对硫酸和硝酸氧化作用的差异提出了一种解释。综合结果使我们能够提出发生在纳米管表面上的可能反应机制。

英文摘要:

The results of a study on the evolution of HiPco single-walled carbon nanotubes during the oxidizing action of H2SO4 and HNO3 are presented. The process conditions used have been chosen so as to avoid any significant damage to the nanotube structure. The type and level of functionalization, the location of the grafted functions on the surface of the nanotube and the changes in morphological characteristics of the samples were examined by using a wide and complementary range of analytical techniques. We propose an explanation for the differences in the oxidizing action of sulfuric and nitric acids. The combined results allow us to suggest possible reaction mechanisms that occur on the surface of the nanotube.
