本研究将一种成熟而温和的分散方法与高质量的弧光放电单壁碳纳米管(SWCNTs)相结合，作为起始材料。因此，我们在制备透明、导电膜方面取得了进展，在单壁碳纳米管加工过程中具有极低的材料损耗。采用热重分析、高分辨电子显微镜和拉曼光谱等手段对原料进行了表征。通过紫外、可见光吸收光谱和拉曼光谱对原料和制备的分散体的质量进行了评价。采用滴注法制备了透明导电膜，得到的薄膜的电光比(σDC/σOp)高达2.2，并且在加工过程中纳米管材料的损耗远低于20wt%。将文献中描述很好的高压一氧化碳转化(HIPCO)单壁碳纳米管用于比较。
This study addresses a combination of a well-developed and mild dispersion method and high-quality arc discharge single-walled carbon nanotubes (SWCNTs) as starting materials. Thus, we advance in fabrication of transparent, conducting films with extraordinary low material loss during SWCNT processing. The starting material was characterized by means of thermogravimetric analysis, high-resolution transmission electron microscopy and Raman spectroscopy. The quality of the starting material and produced dispersions was evaluated by ultraviolet and visible light absorption spectroscopy and Raman spectroscopy. A transparent conductive film was fabricated by drop-casting, whereas films were obtained with electrical to optical conductivity ratios (σDC/σOp) as high as 2.2, combined with a loss of nanotube material during processing well below 20 wt%. High pressure carbon monoxide conversion (HiPCO) SWCNTs, which are very well described in the literature, were used for comparison.
