    Abstract: 本論文開發出兩種含親水端之 NB 單體,分別製備兩系列高親水端高分子。同時開發兩種含親水端之 St單體,製備出第三系列高親水端高分子。
    第一系列 NB 高分子以開環移位聚合反應 (Ring-Opening Metathesis Polymerization, ROMP) 進行聚合,將具親水性的 NB-IM-I 和具疏水性的 NB-Hex 在第二代 Grubbs 催化劑的催化下進行ROMP 聚合,得到 PNB-IM 高親水端之無規高分子。此系列高分子經由工研院後續加工成膜,PNB-CIM-90 在常溫去離子水中導電度最高可達 0.13 S/cm。第二系列高分子乃將新開發之具親水性的 NB-CIM-I 和具疏水性的 NB-Hex 同樣進行 ROMP 聚合,製備出 PNB-CIM之無規高分子。調控反應中親疏水端的當量數比來得到不同比例的親疏水端高分子。此系列高分子薄膜以 PNB-CIM-55 為例,在常溫去離子水中導電度最高可達 0.056 S/cm,而高親水端無規共聚物 PNB-CIM-90 也經由工研院後續加工成膜,在常溫去離子水中導電度最高也達 0.092 S/cm,有望可應用在固態鹼性燃料電池當中。 第三系列高分子以可逆加成鏈轉移自由基聚合法 (Reversible Addition-Fragmentation Transfer, RAFT) 進行聚合,將具有親水性的 [VBIM]Cl 及新開發之單體 [VB-aCIM]I 以 RAFT進行聚合,製備出 PS-IM 與PS-aCIM 兩種高親水端高分子。此系列高分子之陰離子置換為碘離子之後,可作為染料敏化太陽能電池之固態電解質,並搭配本實驗室所開發之有機染敏 TPA-TTAR-TA 製作成元件,其最高光電轉換效率分別可達 6.27 % 以及 6.72 %。
    ;In this study, three series of anion exchange membranes were developed. First, PNB-IM was prepared via ring-opening metathesis polymerization (ROMP) of hydrophilic NB-IM and hydrophobic NB-Hex by using second generation of Grubbs catalyst. Highly hydrophilic PNB-IM (R-90) exhibits the highest ionic conductivity of 0.13 S/cm in deionized water at room temperature. Second, PNB-CIM was prepared via ROMP of hydrophilic NB-CIM and hydrophobic NB-Hex. The ratio of hydrophilic and hydrophobic units in the random copolymer can be controlled by changing the reactant equivalents. PNB-CIM (R-50) show ionic conductivity of 0.056 S/cm. Highly hydrophilic PNB-CIM (R-90) displayed ion conductivity up to 0.092 S/cm. Third, PS-IM and PS-aCIM were prepared via reversible addition-fragmentation transfer (RAFT) of hydrophilic [VBIM]Cl and [VB-aCIM]I. After ion exchange with iodide, these two polymers could be used as solid electrolyte in quasi-solid-state dye-sensitized solar cells. Using TPA-TTAR-TA as dyes, the DSSC exhibits the photoelectric conversion efficiencies of 6.27 % and 6.72 %, respectively.
