摘要:

用CVD法合成晶须状碳纳米管(WCNTs), 对其进行石墨化纯化处理。利用扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线衍射(XRD)、拉曼光谱和热重分析(TGA)对其进行表征。以纤维素为基体材料, WCNTs为功能材料, 将分散好的WCNTs与纸纤维混合, 抽滤制成WCNTs复合纸, WCNTs复合纸的电导率由石墨化前14.1 S/m提升到石墨化后325.1 S/m。采用两电极体系, 以1 mol/L LiPF₆为电解液, 通过循环伏安及恒流充放电方法来研究WCNTs复合纸为极片的超级电容器性能, 在扫描速率为1 mV/s时, 石墨化WCNTs复合纸电极的比容量达到90 F/g。在电流密度为800 mA/g时, 比能量和比功率分别为21.3 Wh/kg和2.1 kW/kg, 表现出良好的超级电容器性能。

Abstract：

Whisker-like carbon nanotubes (WCNTs) were produced by chemical vapor deposition (CVD) and then purified by graphitization at high temperature. The WCNTs were characterized by scanning electron microscope (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Raman spectra and thermogravimetric analysis (TGA). Water suspension consisted of WCNTs as functional material and cellulose fibers as matrix was prepared by speed-cutting procedure, and then WCNTs containing composite papers were prepared with the above suspension by vacuum filtration. The conductivity of the composite papers increased from 14.1 S/m to 325.1 S/m after incorporation of the graphitized WCNTs. A supercapacitor cell with two-electrodes was constructed with 1 mol/L LiPF₆ as electrolyte. The electrochemical performance of supercapacitor was examined by cyclic voltammetry and galvanostatic charge/discharge. The results indicated that the supercapacitor has a maximum capacitance of 90 F/g by a scan rate of 1 mV / s. The specific energy and specific power reached 21.3 Wh/kg and 2.1 kW/kg respectively by a current density of 800 mA/g. These showed an excellent application prospect of the modified carbon nanotubes for supercapacitors.
