中文摘要 | 本研究針對聚苯胺(PAni)和三氧化鎢(WO�陛^組成的「有機-無機」互補式電致色變系統進行最適化設計。元件中PAni與WO�偭■中嬪O以電化學法及溶膠-凝膠法製得。藉由電化學循環伏安掃瞄(CV)配合同步光學量測,得到元件的穿透率vs.掃瞄時間之關係圖、穿透率vs.操作電位響應圖、以及cv圖,並藉由這些特性曲線決定元件的安全操作電位範圍為 +1.0V到 -0.3V之間。實驗證實工作電極的選取不影響互補式元件之工作性能,且元件的變色反應受限於電量密度較小的一極。當以兩電極的電量密度比作為最適化設計參數時,實驗結果顯示元件的最適化設計條件為『兩極的電量密度相等』。本研究提供電致色變元件設計上簡單、初步的線索。 |
英文摘要 | This research mainly focuses on the optimal design of the hybrid organic/inorganic complementary electrochromic device (ECD), comprising a polyaniline (PAni) and tungsten oxide (WO��) thin film couple in combination with a proton-conducting polymer electrolyte. The primary motivation of the present investigation is to examine the connection between the optical attenuation range and the charge capacity ratio of WO�� relative to PAni. Various experiments were done to characterize both the electrochromic thin films and the devices. The safe operating voltage of the device can be determined from these data and ranging from +1.0V to -0.3V. It was found, experimentally, that the performance of the complementary ECD is limited by the electrode with the least charge capacity, and the performance is invariant regardless of the choice of the working electrode. Furthermore, it has been shown experimentally that, for two complementary electrochromic layers each with an individual thickness, the charge capacities of the two electrochromic layers have to be matched in order to achieve the maximum optical attenuation range. That is, the principle of optimal design is to equalize the charge capacity on both electrochromic layers. |
