摘　　要：为了避免电化学反应对电子纸显示电极和显示材料的损坏，用PVA（聚乙烯醇）、PET（聚酯）和PI（聚酰胺）等惰性高分子材料对ITO（氧化铟锡）薄膜电极进行了修饰，并通过原子力显微镜、电化学工作站以及红外、紫外可见光光谱分析等手段对修饰效果进行了研究。通过红外光谱和电化学工作站，研究了金属络合染料在电极上发生的电化学反应，通过紫外可见吸收光谱，研究了染料和颜料在电极保护层上的吸附与染色。试验结果表明，PI在ITO薄膜玻璃电极上粘接牢固，涂层致密，绝缘效果良好，能够有效地避免显示材料在电极上的电化学反应。To protect electrode or electrophoresis media from electrochemical damage in e-paper displaymg, electrically inert polymers such as PVA, PET and PI were used to modify ITO electrode. Protection effectiveness was studied by the means of atomic force microscope （AFM）, cyclic volt-ampere curve, IR spectrophotometry, UV-Vis spectrophotometry and etc. The electrochemical reaction of metal complex dye was tested by IR spectrum and cyclic volt-ampere curve, and the dyeing and absorbing of dyes and pigments on the modified electrode were tested through UV-Vis spectrum. Experimental results revealed that polyamide-imide （PI） was able to firmly adhere onto ITO surface, forming a closely packed, uniform and insulator-like coating and effectively preventing the electrode from electrochemical reaction.
