摘要:
为了改善导电聚吡咯对于抗坏血酸的电化学检测性能，采用以甲基橙为软模板，制备了聚吡咯纳米管。利用扫描电子显微、红外光谱、X射线衍射、X射线光电子能谱对产物的结构与微观形貌进行了表征。分别将聚吡咯纳米管与聚吡咯纳米颗粒对抗坏血酸进行电化学检测。循环伏安测试结果表明，聚吡咯纳米管和聚吡咯纳米颗粒对于抗坏血酸都有明显的电化学响应，同时聚吡咯纳米管的比聚吡咯纳米颗粒的响应电流更大，表明聚吡咯纳米管具有更好的电化学检测能力。差分脉冲伏安法研究发现抗坏血酸浓度在0.5 mmol/L~20 mmol/L和20 mmol/L~45 mmol/L范围内，与峰值电流呈良好的线性关系。这表明聚吡咯纳米管作为电化学传感器材料有很好的应用前景。
Abstract:
To improve the electrochemical performance of conducting polypyrrole for sensing ascorbic acid， the polypyrrole nanotubes were prepared using methyl orange as a soft template. The microstructure and morphology of the products were characterized by scanning electron microscopy， Fourier transform infrared spectrometry， X-ray diffraction and X-ray photoelectron spectrometry， respectively. The electrochemical detection of polypyrrole nanotubes and polypyrrole nanoparticels for ascorbic acid were conducted. The result of cyclic voltammetry indicated that polypyrole nanotubes and polypyrrolenanoparticles both had electrochemical response for ascorbic acid. But the response current of polypyrrole nanotubes was higher than that of polypyrrole nanoparticles， suggesting that the polypyrrole nanotubes had better electrochemical performance. The electrochemical response of polypyrrole nanotubes for sensing ascorbic acid were further investigated by differential pulse voltammetry. The responses of this sensor were linear over the ranges of 0.5 mmol/L to 20 mmol/L and 20 mmol/L to 45 mmol/L， respectively. It indicates that the polypyrrole nanotubes can be used as promising materials in the field of electrochemical sensors.
