摘　　要：以悬铃木果毛纤维为碳源,采用低温预碳化和活化剂刻蚀结合的方法,制备了空心多孔碳微米管材料(HPCT)。通过控制活化剂KOH的比例,优化了材料的结构,得到了电化学性能良好的碳材料。所制备的HPCT直径约为20~30μm,壁厚约为1.5~2μm,具有2135 m^(2)/g的高比表面积。用作水系超级电容器电极时,具有较高的比电容、良好的倍率性能以及循环稳定性。Hollow porous carbon microtubules(HPCT)were prepared by low temperature pre-carbonization and activator etching with platanus acerifolia fruit fibers as carbon source.Carbon material with good electrochemical performance was obtained by optimizing the material structure,which was obtained through controlling the proportion of KOH.The specific surface area of obtained HPCT was high up 2135 m^(2)/g with diameter of 20~30μm and wall thickness about 1.5μm.When used as the electrode of aqueous electrolyte supercapacitor,it has high specific capacitance,good rate performance and cycle stability.
