高透明性含芳香胺結構聚醯胺孔洞膜及混成材料之合成與電致變色特性之研究

Abstract

本論文分成四個章節，第一章為總體序論。第二章為奈米孔洞薄膜在電致變色上的應用。第三章是利用合成新型具有醇類官能基的電致變色高分子，透過溶膠凝膠法結合有機無機材料，並探討其在電致變色上的特性。第四章節為結論。此研究兩個主題皆致力在於改善電致變色的性質，其利用原本就存在於電致變色元件中的電解質來製造奈米孔洞不僅可以使電解質有更高的功能性並且產生能夠產生較多的表面積使的電解質可以更容易滲透，並且在更短的時間之內平衡電荷以達到增進電致變色特性， 其二利用結合有機無機材料使的具有強電子接收能力的金屬氧化物直接鍵結在高分子上，透過電子接收的特性使的氧化還原能進行得更順利，不僅能降低電位同時能夠提升電致變色特性，並且在與紫精衍生物搭配的同時能夠有正向的加乘效果，在元件中有更出色的電致變色特性。

This study has been separated into four chapters. Chapter 1 is the general introduction. In chapter 2, the porous polyamide films were prepared by the salt and the electrochromic behaviors between dense film and porous film have been investigated. In chapter 3, the electrochromic materials (ECMs) were synthesized and hybrids electrochromic devices (ECDs) were prepared. Chapter 4 is the conclusion. The preparation and electrochromic properties of porous polyamide films were investigated. It was a novel method to prepare the porous films by blending the salt in polymer solution, and then the salt in the films would be removed. The electrolyte could have penetrateon to the film more easily through the porous structure. And it also increases the active area of electrochromic process. Because the benefits of porous structure the electrochromic properties were significantly increased. On the other hand, keeping the salt in polyamide films and then washed it by the injected electrolyte, this method could also achieve the similar enhancement of electrochormic properties. In Chapter 3, the novel electrochromic material with hydroxyl group has been successfully synthesized. TiO2 combined with electrochromic material through the sol-gel reactions. TiO2 had strong electron accept ability which promoted the electrochromic material release the electron more easily and quickly, hence the response capability could be enhanced. Arranged the HV(BF4)2 and TiO2 in groups which exhibited additive effect in the ECD. Because of the additive effect, the enhancement of electrochomic properties was better than the single material system.
