| 摘 要： | 以苯胺单体为原料,采用电化学沉积法在玻璃衬底FTO导电薄膜上合成聚苯胺电致变色薄膜.采用恒电流法,研究苯胺单体浓度、酸的种类、电沉积时间、电流密度等对薄膜制备及电致变色性能的影响,确定合成聚苯胺薄膜的最佳条件.结果表明,聚苯胺电致变化薄膜的最佳制备条件是0.15,mol/L苯胺单体的1,mol/L硫酸溶液,以10,μA/cm2的电流密度电沉积40,min.该条件下制备的薄膜的着色效率较无机电致变色薄膜高,但仅能循环105次.

| Abstract: | Polyaniline(PANI)electrochromic films was made onto commercially available FTO conductive glass substrate by galvanostat method with aniline monomer as raw materials.The effects of aniline concentration,acid species,electrodeposition time and density of the current on the electrochromic properties of the PANI film were studied.The best condition of PANI synthesis was 0.15 mol/L aniline in 1 mol/L H2SO4,current density 10 μA/cm2 for 40 min.The results revealed that the film’s coloring efficiency is higher but the layer could cycle only 105 times. |
