【摘要】 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。更多还原

【Abstract】 The composite film of polyaniline/silver(PANI/Ag) was obtained by using high conductivity Ag as additive For the first time,the reversing pulse galvanestatic method was adopted to produce codeposition for PANI and Ag The cyclic volmmatry of the composite film in HNO 3 solution showed that there had a excellent electrochemical properties Furthermore, the influence of prepared conditions on the electrochemical properties of the composite film was investigated The results indicated that, at the following conditions, Ag +concentration 0 01mol/L aniline concentration 0 3mol/L meancurrent density 3～4mA/cm 2 and an appropriate ratio between pulse anodic peak current and pulse cathodic peak current,the best composite film can be obtained更多还原
