摘　　要：使用阳极氧化铝模板制备了阵列聚吡咯纳米棒,并通过电化学沉积技术在聚吡咯纳米棒表面沉积氧化钌,得到基于RuO_(x)-PPy纳米复合材料的超级电容器。通过循环伏安法测试和恒电流充放电测试研究分析RuO_(x)-PPy纳米复合电极的电容特性,结果表明,少量的氧化钌沉积在聚吡咯纳米棒电极上,得到的基于RuO_(x)-PPy的纳米复合电极的电容显著增加,可有效提升电容器的性能。In this paper,arrayed polypyrrole nanorods using anodized aluminum oxide template were prepared,and ruthenium oxide was deposited on the surface of polypyrrole nanorods by electrochemical deposition technology to obtain supercapacitors based on RuO_(x)-PPy nanocomposites.The capacitance characteristics of RuO_(x)-PPy nanocomposite electrodes were studied and analyzed by cyclic voltammetry test and galvanostatic charge-discharge test.The results show that a small amount of ruthenium oxide is deposited on the polypyrrole nanorod electrode,and the RuO_(x)-PPy-based nanocomposite electrode was obtained.The capacitance of the composite electrode is significantly increased,which can effectively improve the performance of the capacitor.
