碳纳米管（CNT）纤维具有高机械强度、高导电性和导热性、良好的耐腐蚀性和抗氧化性以及优异的结构柔性等优异性能，在开发多功能织物方面具有广阔的前景。然而，通过成熟的纺织技术以全自动方式制备仅含有CNT纤维的此类织物仍然是一个巨大的挑战。在这里，我们第一次报道了CNT纤维织物的自动制造。这是通过使用自动纬编机编织由CNT纤维组成的纱线来实现的，所述CNT纤维由基于浮动催化剂化学气相沉积的工艺生产。由此产生的全碳纳米管纤维织物具有柔性、重量轻、机械强度高以及导电和导热性。这种多功能织物的应用前景被证明是通过使用它们作为快速响应的电加热器和作为柔性超级电容器中的高性能织物电极。我们希望这项研究将为CNT纤维在实际应用中的使用铺平新的道路。
With their impressive properties such as high mechanical strength, high electrical and thermal conductivities, good corrosion and oxidation resistance, and excellent structural flexibility, carbon nanotube (CNT) fibers hold great promise for developing multifunctional fabrics. However, the preparation of such fabrics containing only CNT fibers through mature textile technologies in a fully automatic way remains a big challenge. Here, for the first time, we report the automatic fabrication of CNT fiber fabrics. This is achieved through knitting yarns composed of CNT fibers that are produced from a floating catalyst chemical vapor deposition based process using an automatic weft knitting machine. The resulting all-CNT fiber fabrics are flexible, light weight, mechanically strong, and electrically and thermally conductive. The promising applications of such multifunctional fabrics are demonstrated by using them as fast-responding electrothermal heaters and as high-performance fabric electrodes in flexible supercapacitors. We expect that this study will pave a new way for the use of CNT fibers in real-world applications.
