摘要: Electric arc produced single-walled carbon nanotube (SWNT) films have been purified by a selective oxidation process. The purification is monitored Near-infrared (NIR) spectroscopy, which gives quantitative estimate of relative purities. This technique also an the change in amounts nanotubes (SWNTs) and amorphous impurities after each step, thereby providing accurate control over Oxidation was carried out reaction flowing oxygen at 265, 292 315°C for different time durations purity evaluated step compared to starting as-prepared film. Relative purities, SWNTs were as function temperature time. maximum purity, could be obtained present process, three times that SWNT
