摘    要:采用表面过程法拉第阻纳表达式方法与等效电路方法,研究透明ITO平面电极及带WO3薄膜层的ITO平面电极处于1mol LiClO4丙烯碳酸酯电解液中的电化学阻抗谱.分析显示WO3薄膜层有效地阻止了表面吸附参量对ITO电极反应的影响,使电极反应仅受电极电位的影响,并且随WO3薄膜在电解液中浸泡时间的增加,WO3薄膜的常相位角元件的特性最终回归为电容效应.

关 键 词:ITO  电解液  交流阻抗  WO3薄膜

Abstract:The electrochemistry impedance spectroscopies of ITO plane electrodes and ITO plane electrodes with WO3 thin film immersed in 1 mol LiClO4 propylene carbonate electrolyte have been studied by means of the surface process Faraday immittance expression and equivalent circuits. The results show that the effect of the state parameter on ITO electrodes can be prevented by the tungsten oxide thin film and the effect of electrode voltage E remaine. The characteristics of the constant phase angle elements will go back to the characteristics of capacitance of tungsten oxide thin film with the immersed time increasing. The calculational impendances coincide with the experimental results.
Keywords:ITO  electrolyte  impendance  WO3 thin film
