报道了一种高效、通用的在柔性铝箔（厨房用）上用催化剂支撑的化学气相沉积法生长薄层碳纳米管的方法。本实验中使用的铝箔可商购获得用于厨房用途。采用电子束气相沉积法和浸涂法在铝箔上制备催化剂。当乙醇与Fe和Co催化剂颗粒结合使用时，在Ar/H2气流下，在约650 °C的生长温度下，获得典型直径为2.5-6.0 nm且长度高达90 µm的垂直排列的薄层CNT。热重分析和HR-TEM观察表明，由当前技术合成的碳纳米管的纯度是非常高的。
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/H2 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.
