摘要

通过有机化学合成法使苯胺单体接枝到碳纳米管表面, 然后再经化学原位聚合法制备碳纳米管/聚苯胺复合材料. 用傅立叶变换红外光谱和扫描电子显微镜对复合材料的成分和形貌进行表征. 用循环伏安法、恒流充放电和电化学阻抗等电化学测试手段来表征复合材料的电化学性能. 研究结果表明，所制备的复合材料比容量可达到152F/g（有机电解液）, 显著高于同样条件下的纯聚苯胺、纯碳纳米管及由原位化学聚合法所制备碳纳米管/聚苯胺复合材料的电化学容量(65、25、80F/g), 显示出良好的应用前景.

Abstract

The aniline was inarched on the surface of the carbon nanotubes (CNTs) by a series of organic chemistry reactions. Then, the aniline on the surface of the CNTs was polymerized to polyaniline (PANI) by the in situ chemical polymerization. At last, a nanometer composite named as the CNTs/PANI composite was obtained. Constitution and morphology of the obtained CNTs/PANI composite were characterized by Fourier transform infrared spectroscope and scanning electron microscope. And the electrochemical performances of the obtained materials were tested by the cyclic voltammograms, galvanostatic charging/discharging, and electrochemical impedance spectroscopy. The results show that the obtained CNTs/PANI composite has excellent electrochemical capacitance used as the electrode material of the electrochemical super capacitor (about 152F/g in organic electrolyte), which is much more than those of the pure PANI, pure CNTs and the PANI/CNTs composite made by normal in situ chemical polymerization (about 65, 25 and 80F/g in organic electrolyte). And the materials have appeared excellent application foreground in electrochemical energy field.

Key words： CNTs/PANI composite; electrochemical performance; organic chemistry synthesis
