An efficient and versatile growth of thin-layer carbon nanotubes on a flexible aluminum foil (for kitchen use) by catalyst-supported chemical vapor deposition is reported. The aluminum foil used in the present experiment is commercially available for kitchen use. The electron-beam vapor deposition and dip-coating have been used for preparing catalysts on the aluminum foil. Vertically aligned thin-layer CNTs with typical diameters of 2.5-6.0 nm and lengths up to 90 µm are obtained when ethanol is used in combination with Fe and Co catalyst particles at a growth temperature of around 650 °C under an Ar/H(2) gas flow. Thermo-gravimetric analyses together with HR-TEM observations indicate that the purity of the CNTs synthesized by the current technique is very high.
本文报道了一种在商用厨房用铝箔上通过催化剂支持的化学气相沉积法高效且多功能地生长薄层碳纳米管的方法。实验中使用的铝箔可用于厨房。本实验采用电子束蒸发和浸涂法在铝箔上制备催化剂。当在生长温度约为 650°C 下,使用乙醇并结合 Fe 和 Co 催化剂颗粒时,在 Ar/H(2)气流中可得到典型直径为 2.5-6.0nm 且长度高达 90μm 的垂直排列的薄层 CNTs。热重分析和高分辨透射电子显微镜观察表明,当前技术合成的 CNTs 的纯度非常高。
