| 中文摘要: |
| 碳纤维表面呈现化学惰性，缺乏活性官能团，限制了碳纤维作为电化学分析电极的应用。目前，许多手段被用于碳纤维的表面改性处理。采用电化学氧化方法，在磷酸溶液中对碳纤维进行了处理，并进行了红外光谱和循环伏安试验。结果发现：处理后碳纤维的表面接上了活性官能团，大量活性碳原子被剥离出来。在K4Fe(CN)6加KC1、FeS04加HCl04两组混合溶液体系中的电化学响应明显改善，适合作为电化学分析电极。 |
| 英文摘要: |
| Carbon fibers without any modification can be hardly applied as electrochemical electrode due to chemistry inertia and the lack of active functional groups. Up to now, a variety of measures have been taken to modify carbon fibers. Carbon fibers were treated by the electrochemistry oxidation in phosphoric acid solution. Infrared spectrometry and cyclic voltage-ampere analysis were made. The results show that the surface of carbon fibers is modified by fixing active carbon atoms and functional groups. The electrochemical properties of carbon fiber in mixed solutions K4Fe ( CN) 6 +KCl,FeS04 +HCl04 have been improved remarkably. The oxidized carbon fibers are found to be fine electrodes for electrochemical analysis. |
