采用原位氧化聚合法在高氯酸溶液中成功制备了磺化多壁碳纳米管（sMWCNTs）修饰聚苯胺（PANI）纳米棒（PANI/sMWCNTs）复合材料。FTIR和拉曼光谱表明聚苯胺与磺化碳纳米管之间存在π-π相互作用，形成了电荷转移复合物。结果表明，PANI/sMWCNT复合材料的比电容受其形貌结构和PANI含量的影响较大。PANI/sMWCNT复合材料的比电容在PANI含量为76.4wt%时达到最大值515.2Fg-1。充放电测试表明，与聚苯胺纳米棒相比，聚苯胺/sMWCNT复合材料具有良好的循环稳定性（1000次循环后容量损失小于10%）。
The novel composites of sulfonated multi-walled carbon nanotubes (sMWCNTs) modified polyaniline (PANI) nanorods (PANI/sMWCNTs) were synthesized successfully by in situ oxidative polymerization method in the HClO4solution. FTIR and Raman spectra revealed the presence of π–π interaction between the PANI and the sulfonated carbon nanotubes and the formation of charge transfer composites. It was found that the specific capacitance of the PANI/sMWCNT composites was markedly influenced by their morphological structure and the content of PANI which was coated onto the sMWCNT. The specific capacitance of the PANI/sMWCNT composite exhibited a maximum value of 515.2Fg−1at the 76.4wt% PANI. The charge–discharge tests showed the PANI/sMWCNT composites possessed a good cycling stability (below 10% capacity loss after 1000 cycles) compared to PANI nanorods.
