| 摘 要： | 本文通过加入过硫酸铵(APS)引发苯胺和丙烯酸(AA)在水溶液中的协同聚合反应，一步合成出具有中空结构的聚苯胺纳米管. 聚苯胺纳米管的外径平均为180 nm，内径约80 nm，其形成取决于苯胺与丙烯酸的摩尔比(X{ani/AA}). 当X{ani/AA}不超过1时，主要得到聚苯胺纳米管. 在三电极体系中测定了所制备的聚苯胺纳米管的电化学性能. 在1 mol/L H2SO4为电解液，电流密度为0.5 A/g的条件下，聚苯胺纳米管比电容高达436 F/g，是通常聚苯胺纳米片的七倍. 此外，在0.5 A/g的电流密度下进行500次充放电循环后，其比电容能够保持最初始的89.2%，表现出优异的充放电循环稳定性.

| Abstract: | The electrochemical property of electrode materials greatly depends on their morphologies. This report introduces a novel and facile synthesis method for polyaniline (PANI) nanotubes from one-step synergistic polymerization of aniline and acrylic acid in an aqueous solution induced by the addition of ammonium persulfate (APS). The molar ratio of aniline to AA (X{ani/AA}) is found to have great in fluence on the morphology of the produced PANI. Hollow PANI nanotubes with an average inner diameter of 80 nm and outer diameter of 180 nm can be mainly produced when X{ani/AA} is not higher than 1. The electrochemical properties of the prepared PANI nanotubes have been investigated using a three-electrode system. The specific capacitance of PANI nanotubes can reach 436 F/g at a current density of 0.5 A/g in 1 mol/L H2SO4 solution. Furthermore, the specific capacitance of the PANI nanotube maintains 89.2% after 500 charging/discharging cycles at a current density of 0.5 A/g, indicating a good cycling stability. |
