摘　　要：采用酸溶液处理方法对垂直于衬底生长的碳纳米管阵列的纯化进行了研究. 利用扫描电子显微镜、X 射线光电子能谱等手段对纯化前后的碳纳米管阵列的结构、形貌及化学组成进行表征. 实验结果表明, 通过控制条件, 酸溶液处理方法能够在有效地去除催化剂粒子等杂质的同时又保持阵列的相对完整性. 纯化后的碳纳米管阵列会促进其在电子学领域的进一步应用.A simple acid treatment method was applied to remove the catalyst impurities and other residues contaminated in the vertically aligned carbon nanotube arrays. We demonstrated that acid treatment was an efficient approach for aligned carbon nanotube purification. Scanning electron microscopy and X-ray photoelectron spectroscopy were used to characterize the morphology of the aligned carbon nanotube arrays and to determine the efficiency of the purification. Using hydrochloric acid could efficiently eliminate catalyst impurities and retain the original structures of the aligned carbon nanotube arrays. The method provided a simple, economical, and effective way to purify the aligned carbon nanotubes, and it would promote the applications of vertically aligned carbon nanotube arrays in electronics field.
