本實驗中合成出八種離子液體，包含四種咪唑系列離子液體以及四種環胺系列離子液體，經由核磁共振分析確定結構。藉由黏度、密度管及導電度計量測其物理性質。並經由熱重分析儀和微差熱掃描卡計分別量測離子液體的熱裂解溫度與相轉移峰。
將八種離子液體各別摻混高分子和塑化劑，均勻混和、塗佈於玻璃上，抽離溶劑製成高分子電解質膜。取膜以恆電位儀測試膜導電度，以摻混Pyr3NO製成的高分子電解質膜之膜導電性最佳，在393.15K下可達3.22×10-3 S cm-1。
使用tris[4-(2-thienyl) phenyl]amine (TTPA) 和 3,6-di(thiophen-2-yl)-9H- carbazole(BTC) 共聚物為陽極材料 ; 陰極選用3,3-diethyl-3,4-dihydro-2H-thieno-
[3,4-b][1,4]dioxepine (PProDOT-Et2)，將高分子電解質各別置於兩電極中，組裝成電致變色元件。
最後使用恆電位儀與紫外光/可見光光譜儀，觀察其穿透度差值、穩定性、轉換時間、著色效率及光學記憶。而離子液體Aze4NO所製成的元件具有最大的光學對比差，約達40.0%。

Four imidazolium-based and four cyclic ammonium-based ionic liquids (ILs) are synthesized, and they are identified using NMR. The physicochemical properties of ILs are characterized using viscometer, dilatometer, and conductivity meter. The thermal decomposition temperatures and phase transition peaks are determined using thermogravimetric analyzer and differential scanning calorimeter.
The eight ILs / polymer composite electrolytes are prepared using solution-casting method. Each IL, polymer, plasticizer, and solvent are stirred for couple hours, the mixture is coated on the glass and vacuum-dried to eliminate solvent thoroughly. The conductivity of Pyr3NO/polymer composite electrolyte film shows the best conductivity, which is 3.22×10-3 S cm-1 at 393.15K.
Electrochromic devices (ECDs) employ poly (TTPA-co-BTC) as anodic material, poly(3,3-diethyl-3,4-dihydro-2H-thieno-[3,4-b][1,4]dioxepine) (PProDOT-Et2) as cathodic material, and IL / polymer composite electrolyte as the separator between two electrodes are constructed.
The optical contrast, stability, switching time, coloration efficiency, and optical memory of ECDs are characterized using a potentiostat and a UV-visible spectrophotometer Among eight ECDs, poly (TTPA-co-BTC) / Aze4NO-polymer composite / PProDOT-Et2 ECD shows the highest optical contrast, and ΔTmax of the ECD is ca. 40%.
