Summary: | 碩士 === 國立中央大學 === 化學學系 === 103 === 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.
