摘　　要：为拓展碳纳米管的实际应用 ,对碳纳米管应用于超级电容器的电极材料的特点作了深入分析。碳纳米管电极具有独特的孔隙结构和高比表面积利用率 ;碳纳米管表面可以形成丰富的官能团 ,具有较好的吸附特性。此外 ,作者提出了采用酸处理或球磨工艺打断碳纳米管、提高其内腔利用率的方法。可以预料 。The features of carbon nanotube electrodes for fabricating supercapacitors were analyzed to provide data for practical application of carbon nanotubes. Carbon nanotube electrodes exhibit unique pore structure and high utilization efficiency of specific surface areas. Carbon nanotubes have excellent absorbtion characteristics due to the abundant surface functional groups. In addition, some processes were proposed for breaking the tubes to enhance the utilization efficiency of the inner cavity of the carbon nanotubes. The results show that carbon nanotubes will have many advantages in this field.
