以高导电率的Ag作为添加材料 ,首次采用换向脉冲电流法使PANI和Ag发生共沉积 ,制成PANI/Ag复合电极。并用循环伏安研究了复合电极在硝酸溶液中的电化学性能及沉积过程中电化学参数对膜层电化学性能的影响。当Ag+浓度为 0 0 1mol/L ,苯胺浓度为 0 3mol/L ,沉积平均电流密度为 3~ 4mA/cm2 ,且脉冲阳极峰电流和阴极峰电流比值适当时可获得电化学性能最为优异的膜层。
With high conductivity of Ag as an additive material, the first time using a commutation pulse current PANI and Ag co-deposition occurred, made of PANI / Ag composite electrode. The electrochemical performance of the composite electrode in nitric acid solution was studied by cyclic voltammetry and the influence of electrochemical parameters on the electrochemical performance of the coating during deposition. When the Ag + concentration is 0 0 1mol / L, the aniline concentration is 0 3mol / L, the deposition average current density is 3 ~ 4mA / cm2, and the ratio of pulsed anode peak current to cathode peak current is appropriate, the most excellent electrochemical performance Floor.
