| Summary: | 碩士 === 國立臺灣大學 === 高分子科學與工程學研究所 === 105 === 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.
