柔性透明导电膜（TCFs）是促进柔性和可折叠器件（包括触摸面板、显示器、有机太阳能电池等）发展的关键。我们通过喷涂法在聚对苯二甲酸乙二醇酯（PET）基底上制备了大面积、柔性、中性颜色的单壁碳纳米管：十二烷基苯磺酸钠/聚（3，4-乙二氧噻吩）：聚（4-苯乙烯磺酸盐）（SWCNT：SDBS/PEDOT：PSS）复合TCF。TCF的薄层电阻为178 Ω sq− 1，在550 nm处的透射率为85%。通过改变单壁碳纳米管的质量分数可以调节薄膜的透光特性。当单壁碳纳米管的质量分数高于4 wt.%时，TCF的原始蓝色色调已经消失。更重要的是，我们发现SDBS作为PEDOT：PSS复合膜的二次掺杂剂，在提高PEDOT：PSS复合膜的导电性能方面可能比单壁碳纳米管网络发挥更重要的作用，这与传统的理解和现有的关于PEDOT：PSS复合膜导电机理的解释不同。
Flexible transparent conductive films (TCFs) are vital to promote the development of flexible and foldable devices including touch panels, displays, organic solar cells,etc.We have prepared a large-area, flexible, and color-neutral single-wall carbon nanotube:sodium dodecylbenzene sulfonate/poly-(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (SWCNT:SDBS/PEDOT:PSS) composite TCF on a poly(ethylene terephthalate) substrate by a spray coating method. The TCF has a sheet resistance of 178 Ω sq−1with 85% transmittance at 550 nm. The light transmission characteristics of the films can be tuned by changing the mass fraction of SWCNTs. When the mass fraction of SWCNTs is higher than 4 wt.%, the original blue tint of the TCFs has disappeared. More importantly, we find that SDBS may play a more important role than the SWCNT network in improving the electrical conductivity of the films by acting as a secondary dopant of PEDOT:PSS, which is different from the traditional understanding and existing explanation about the conduction mechanism of PEDOT:PSS-based composite films.
