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.

Abstract

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 electrolyte-activation,acid-activation or electrochemical activation.The performance of the capacitor based on activated ACNTs 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.
