中文摘要：
在石英玻璃基底上，以酞菁裂解法低压气相沉积制备大面积管径均匀、长度一致的直立碳纳米管．分别应用电解质溶液浸润、酸处理和循环伏安扫描等3种不同方法纯化活化该直立碳纳米管，并以活化后的碳纳米管作为原型超级电容器的电极．循环伏安扫描和交流阻抗测试表明，CV曲线呈近似矩形，交流阻抗最大相位角超过80°，该直立碳纳米管的比电容为16～32F／g，乃超级电容器理想的电极材料．
英文摘要：
Large scale vertically aligned carbon nanotubes （ACNTs） with uniform length and diameter were prepared by the pyrolysis of iron（ Ⅱ ） phthalocyanine at low pressure. The ACNTs were activated by electrolyteactivation, acid-activation or electrochemical activation. The performance of the capacitor based on activated AC- NTs was characterized by cyclic voltammograms which was of rectangular shape, impedence spectroscopy in which the phase is above 80° and the result specific capacitance was 16 - 32 F/g, which suggest that the ACNTs are the promising material for the supercapacitor.
