The purpose of our study is to fabricate optically transparent, electrically conductive film using a high purity double walled carbon nanotubes. The accomplishments throughout this work are summarized as follows. (1) We have established a way of dispersing DWNTs using different types of dispersing agents under the strong sonication and the following ultra-centrifugation process. The individualization of nanotubes in suspension was verified by photoluminescence and UV absorption spectra studies. (2) We have fabricated optically transparent, electrically conductive polyimide film by incorporating individualized DWNTs. (3) It is demonstrated that the defects on the sidewall of tubes acted as an additional driving force to disperse tubes in solution. (4) We have fabricated transparent, mechanically strong, thermally and electrically conductive polyurethane composite. (5) We have fabricated DWNT-derived transparent conductive film using a nano-dipper. Such film exhibiting 85% of transparency as well as low electrical resistivity (180Ω/sq) will replace ITO in OLEL and LCD.

本研究的目的是利用高纯度的双壁碳纳米管制备光学透明的导电薄膜。现将这项工作取得的成就概述如下。(1)我们已经建立了一种分散DWNTs的方法，使用不同类型的分散剂下的强超声和以下的超离心过程。通过光致发光和紫外吸收光谱研究验证了悬浮液中纳米管的个体化。(2)我们已经制作了光学透明，导电聚酰亚胺薄膜，将个性化的DWNTs。(3)结果表明，管侧壁上的缺陷作为一个额外的驱动力，分散在溶液中的管。(4)我们已经制造了透明的，机械强度高的，导热和导电的聚氨酯复合材料。(5)我们已经制作了DWNT衍生的透明导电膜使用纳米勺。这种薄膜具有85%的透明度和低电阻率（180Ω/sq），将取代ITO在OLED和LCD中的应用。
