【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．更多还原

【Abstract】 To protect electrode or electrophoresis media from electrochemical damage in e-paper displaying,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.更多还原
