配合物1由阴离子缩短的单壁碳纳米管和阳离子铵脂质溶解在有机溶剂中合成，在较高相对湿度下浇铸在预处理的透明柔性聚对苯二甲酸乙二醇酯（PET）膜上，形成具有自组织蜂窝结构的薄膜。通过改变实验条件可以控制泡孔尺寸。脂质是复合物1的阳离子部分，可以通过简单的离子交换方法轻松去除，同时保持基本的蜂窝结构。离子交换后，具有更薄骨架的PET上的纳米管蜂窝膜表现出从绝缘到导电的表面电阻率的急剧下降。碳纳米管在柔性聚合物薄膜上自组织形成蜂窝状结构，在纳米材料、纳米电子学、纳米器件、催化剂、传感器等纳米科学技术领域有着广泛的应用前景。
Complex 1, synthesized from anionic shortened single‐walled carbon nanotubes and cationic ammonium lipid dissolved in organic solvents, is cast on pretreated transparent flexible poly(ethylene terephthalate) (PET) films under a higher relative humidity to form thin films with self‐organized honeycomb structures. The cell sizes are controllable by changing the experimental conditions. The lipid, which is the cationic part of complex 1, is easily removed by a simple ion‐exchange method, while maintaining the basic honeycomb structures. After the ion exchange, the nanotube honeycomb films on PET with thinner skeletons exhibit a dramatic decrease in the surface resistivity from insulating to conducting. Carbon nanotubes with honeycomb structures formed by the self‐organization on flexible polymer films are useful in many areas of nanoscience and technology including nanomaterials, nanoelectronics, nanodevices, catalysts, sensors, and so on.
