Alignment of carbon nanotubes (CNTs) in CNT/polymer composite films is an attractive technique to obtain improved electrical, mechanical, and thermal properties. However, their alignment method is still confined to small laboratory scale sample preparation. In this letter, a novel method to prepare a continuous drawing of ribbon-like films of CNT/polymer composite is proposed using a robotic dispenser. We prepared 400 to 2000 m wide oriented ribbon of CNT/polymer films that can be used for roll-to-roll processing in length scale. CNTs were found to be aligned along the drawing direction as confirmed by polarized Raman mapping and scanning electron microscope images.

使用机器人分配器制造定向控制的碳纳米管/聚合物复合材料的带状薄膜

碳纳米管（CNT）在碳纳米管/聚合物复合膜中的排列是一种有吸引力的技术，可以改善电气、机械和热性能。然而，他们的对齐方法仍然局限于小实验室规模的样品制备。在这封信中，提出了一种使用机器人分配器连续拉伸碳纳米管/聚合物复合材料的带状薄膜的新方法。我们制备了 400 到 2000 m 宽的 CNT/聚合物薄膜定向带，可用于卷对卷长度加工。通过偏振拉曼映射和扫描电子显微镜图像证实，碳纳米管沿拉伸方向排列。
