本論文中採用聚苯胺(PANI)和聚二氧乙基塞吩(PEDOT)來組裝成可撓曲式電致變色元件。論文中分做兩部分來探討，第一部份是在單一電極中，分別針對PANI於不同摻雜物(CSA和PSS)下及PEDOT-PSS本身的電致變色行為進行討論。而第二部分則探討利用此兩種電致變色材料為兩電極組裝而成的可撓曲式電致變色元件，並進行電致變色特性探討。
（1）單一電極之電致變色行為
　　PANI摻雜PSS之後，會形成交聯的構造抑制劣化產物或PANI寡聚物的氧化還原反應進行，改善PANI本身的電化學、電致變色及熱穩定等性質。而這些皆可經由循環伏安掃描、紫外光/可見光光譜、化學分析、熱重分析及導電度測試的結果來獲得證實。PEDOT-PSS本身之應答時間與PANI系統相近，所以適合用來當作PANI之互補電極。
（2）可撓曲式電致變色元件電致變色行為
　　利用聚苯胺以及聚二氧乙基塞吩當作互補電極，聚氧化乙烯(PEO)摻雜LiClO4為高分子電解質，進行可撓曲式電致變色元件之製作，並探討元件特性。元件PES-ITO / PANI-PSS || PEO-PC-LiClO4 || PEDOT-PSS / ITO-PES有較可逆的氧化還原特性(庫倫效率接近100 %)以及較佳之元件穩定度，並且在撓曲的狀態下並不會改變其電致變色特性。

　In these studies, a flexible electrochromic device was fabricated by using PANI and PEDOT as chromic materials. The results and discussions of these studies are presented in two parts.

　In the first part, the evaluations of electrochromic properties of single electrodes (PANI-CSA, PANI-PSS and PEDOT-PSS) are disscussed. In the second part, we discuss the electrochromic properties of a flexible electrochromic device which was tested by the assembling of PANI and PEDOT as chromic materials.
（1）Electrochromic properties of single electrodes
　The incorporation of the polyelectrolyte (PSS) in PANI affected the electrochemical, electrochromic properties, morphology, and polymer structure of the polymer film as evidenced by the results of cyclic voltammetry, in-situ uv-visible spectroscopy, x-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), thermogravimetric analysis and conductivity measurements. PANI doped with PSS was found to have a crosslink/branched structure and retarded the formation of degradation products or oligormers. The suppressed formation of degradation products can improve the electrochemical, electrochromic and thermal stability.
　According to the analysis of electrochemical and electrochromic properties of PANI-CSA, PANI-PSS and PEDOT-PSS, it prompted us to PANI-CSA/PANI-PSS and PEDOT-PSS as electrodes for fabrication of the complementary electrochromic devices.
（2）Electrochromic properties of flexible electrochromic devices
　Film of PANI and PEDOT on ITO glass was used as the electrodes with LiClO4 doped gelled polyethylene oxide (PEO) as polymer electrolyte. The electrochromic devices with the following configuration were assembled:
PES-ITO/PANI(doped CSA or PSS)||PEO-PC-LiClO4||PEDOT-PSS/ITO-PES
　In the discussions of electrochromic properties, we find PES-ITO/PANI-PSS||PEO-PC-LiClO4||PEDOT-PSS/ITO-PES device has better quality, included the interconversion of coloring state and bleaching state is more complete and lead to better stability.
　Further, PANI-PSS used flexible electrochromic device did not change its electrochromic properties that the device is in the bending state.
