| 摘 要： | 采用电势阶跃技术, 于Pt微盘电极上在含水体积分数分别为0, 2%, 4%, 6%和8%的0.1 mol/L Pyrrole+0.1 mol/L LiClO4的碳酸丙烯酯(PC)溶液中合成了聚吡咯(PPy)膜. 采用循环伏安法、计时电流法考察了不同含水比例条件下聚吡咯的电化学行为, 采用扫描电镜对其表面形貌进行了观察分析. 研究结果表明, 最佳的含水体积分数为6%. 在此条件下聚合得到的PPy量大, 具有较高的电化学容量、较好的电化学反应可逆性.

| Abstract: | Using potential step method,polypyrrole films were synthesized directly on the surface of Pt micro-disk electrode in 0.1 mol/L pyrrole-0.1 mol/L LiClO4-PC solution containing different proportion of water(0,2%,4%,6%,8%,in volume fraction).The electrochemical properties of polypyrrole film electrodes were characterized with the methods of cyclic voltammetry(CV) and chronoamperometry,the morphologies of films were observed by scanning electron microscope(SEM) as well.It is shown that the addition of 6% water ... |
