采用微波等离子体增强化学气相沉积法在氢等离子体处理过的碳纳米管基体上制备了碳纳米片。结果表明，碳纳米管的直径先变粗，然后在碳纳米管的外壁上生长出花瓣状的碳纳米片。无碳纳米片和有碳纳米片的碳纳米管的直径分别为100-150和300 - 500 nm。拉曼光谱表明碳纳米管/碳纳米片为石墨结构。氢等离子体处理和反应时间对碳纳米片的生长和密度有很大影响。基于上述结果，碳纳米片/碳纳米管可能作为冷阴极材料和电极材料具有重要的应用。(c)2007 Elsevier B. V.保留所有权利。
Carbon nanosheets were synthesized by microwave plasma-enhanced chemical vapor deposition method on carbon nanotubes substrate which was treated by hydrogen plasma. The results showed that the diameters of carbon nanotubes first got thick and then "petal-like" carbon nanosheets were grown on the outer wall of carbon nanotubes. The diameters of carbon nanotubes without and with carbon nanosheets, were 100-150 and 300500 nm, respectively. Raman spectrum indicated the graphite structure of carbon nanotubes/carbon nanosheets. The hydrogen plasma treatment and reaction time greatly affected the growth and density of carbon nanosheets. Based on above results, carbon nanosheets/carbon nanotubes probably have important applications as cold cathode materials and electrode materials. (c) 2007 Elsevier B.V. All rights reserved.
