| Summary: | 碩士 === 國立高雄應用科技大學 === 化學工程與材料工程系博碩士班 === 104 === Two homopolymers (poly(4,4′-bis(N-carbazolyl)-1,1′-biphenyl) (PCBP) and poly(indole-6-carboxylic acid) (PI6CA)) and three copolymers (P(CBP1-co-I6CA1), P(CBP1-co-I6CA2), and P(CBP1-co-I6CA4)) with various CBP/I6CA feed molar ratios are electrochemical polymerized on ITO electrode. The P(CBP1-co-I6CA2) can change between yellow in the reduced state and greyish black in the oxidized state. The optical contrast (Tmax, 32.2 %) of P(CBP1-co-I6CA2) film at 767 nm is higher than that of PI6CA at 724 nm (19.3 %). Five dual-type electrochromic devices (ECDs) are fabricated using the CBP- and I6CA-based polymers as coloring layers, and poly(3,4-(2,2-diethylpropylenedioxy)thiophene) (P(ProDOT-Et2)) as the complementary layer with hybrid polymer electrolytes as gel electrolytes. The ECD fabricated using anodic copolymer P(CBP1-co-I6CA2) with a CBP/I6CA feed molar ratio of 1/2 has the highest optical contrast (41.0%) and coloration efficiency (249.27 cm2 C-1) at 587 nm. In addition, this ECD has satisfactory optical memory effect and long-term cycling stability.
