中文摘要：
以管状二氧化锰（MnO2）为氧化剂和模板剂在酸水体系中化学氧化制备了聚苯胺（PANI）纳米管。采用能谱仪、扫描电镜、透射电镜、红外光谱、循环伏安、恒流充放电及交流阻抗谱等测试手段对其结构和电化学性能进行测试；研究不同苯胺单体（ANI）的用量对PANI结构和电化学性能的影响。结果表明，制备的聚苯胺为内径约90nm，外径约350nm，长约2μm的纳米管；在m（Mn02）：m（ANI）=9：25时，合成的PANI管状结构比较丰富，在1mol／LH。SO。电解液中比电容达到473F／g。
英文摘要：
Polyaniline nanotubes （PANI） were successfully prepared using tubular manganese dioxide as oxidant and template in acid water system. The structure was characterized by using energy dispersive X-ray spectrosco- py （EDX）, scanning electron microscopy （SEM）, transmission electron microscopy （TEM） and Fourier trans.- formation infrared spectroscope （FT-IR） ; and the supercapacitive behaviors of the materials were investigated with cyclic voltammetry （CV）, charge-discharge tests and electrochemical impedance spectroscopy （EIS）, re- spectively. The effects of aniline （AND amount on the structure and electrochemical performance of prepared PANI were discussed in detail. The results indicate that the prepared PANI present nanotube morphology with inner diameters of about 90nm, outer diameters of about 350nm and lengths of about 2μm; when feed ratio of manganese dioxide （MnO2） to ANI was changed from 9 to 25, a maximum specific capacitance （SC） of as-pre- pared PANI nanotubes of 473F/g could be achieved in lmol/L aqueous H2SO4.
