Study on Polymer-Modified Electrodes

开发了聚合物修饰电极，并将其应用于电致变色显示。将聚共季化3,4-四吡啶卟啉（Poly-Co-QTPP）薄膜通过电化学还原修饰在铟锡氧化物（ITO）玻璃上，制备了存储型电致变色显示器。在1.0M KCl水溶液中，薄膜电极与饱和焦糖电极（SCE）相比受到-1.4 V的负电位，得到紫色薄膜。在+1.8 V vs. SCE的正电位下，薄膜的颜色恢复为绿色。由于聚合物结构，与单体膜相比，Poly-Co-QTPP膜在重复操作中表现出优异的耐久性。此外，在不通电的情况下，还原状态的薄膜可以长时间保存3个月以上。

The polymer-modified electrodes were developed and applied to the electrochromic display.A storage type electrochromic display was fabricated by a Poly-Co-quarternized 3,4-tetrapyridinoporphyrazine(Poly-Co-QTPP)film which was modified on an In-Sn oxide(ITO)glass by electrochemical reduction. A violet-coloured film was obtained when the film electrode was subjected to a negative potential of -1.4 V vs. a saturated caromel electrode(SCE) in a 1.0M KCl aqueous solution. The colour of the film reverted to green at a positive potential of +1.8 V vs. SCE. As a result of the polymeric structure, the Poly-Co-QTPP film demonstrated excellent durability in repeated operation compared with a monomeric film. Furthermore, the reduced state of the film was stored for a long period of more than three months without electric power.
