摘　　要：碳纳米管具有优秀的导电性能、透光性能和十分突出的柔性,在柔性透明导电薄膜中有着良好的应用前景.如何制备同时拥有良好导电性能和透光性能的碳纳米管薄膜是这一领域研究的核心问题.本综述介绍了碳纳米管薄膜的制备方法,并重点讨论了基于漂浮催化剂化学气相沉积法的碳纳米管薄膜的可控制备.在生长过程中限制碳纳米管的团聚、增加碳纳米管的长度、降低杂质的含量是提高碳纳米管薄膜性能的主要策略.Carbon nanotubes have excellent electrical conductivity,light transmission properties,and outstanding flexibility,which gives them great application potential in flexible transparent conductive films. Preparation of carbon nanotube films with both good electrical conductivity and light transmission properties is the critical issue in this field. This review introduces the preparation methods of carbon nanotube films,and focuses on the controlled preparation of carbon nanotube films based on floating catalyst chemical vapor deposition. During the growth process,limiting the bundling of carbon nanotubes,increasing their length,and reducing the impurities are the main strategies to improve the performance of carbon nanotube films.
