本研究利用電化學式掃描穿隧電子顯微鏡(EC-STM)，即時觀測單體苯胺(Aniline)在單晶金(111)電極表面的吸附機制，研究結果顯示單體苯胺具有兩種吸附結構，√2× √3與2√3× 2√13。此外，利用XPS分析初步判定對苯二硫醇(1,4-Benzenedithiol, 1,4-BDT)的自組裝行為是以單個硫醇官能基與金屬表面鍵結並且以特定角度傾斜於表面上。接著，進一步利用表面增強紅外線光譜(Surface-Enhanced Infrared Adsorption Spectroscopy, SEIRAS)和即時拉曼圖譜(In-situ Raman)結合電化學系統，即時觀測單體苯胺與聚苯胺在單晶金(111)電極表面的分子振動模式，該結果指出不同電位下，造成聚苯胺結構的電子得失，從而改變圖譜中特徵峰的強度。
基於上述結果，提供我們對聚苯胺和對苯二硫醇的表面特性和反應機制有更全面的了解，再者，利用硫醇-烯點擊反應(Thiol-ene click chemistry)技術開發兩種製備硫醇化聚苯胺(Thiolated Polyaniline)薄膜的方式並利用循環伏安儀測試薄膜的電化學特性和電容性質，其中硫醇摻雜於聚苯胺薄膜之製備方法表現出最佳的電化學特性和電容性質，得以應用於超級電容器元件，藉由選擇基板、電解質的組成和比例調控，以及電極表面上薄膜的選擇，找到超級電容元件的最適化參數，並且比較相同參數下的硫醇化聚苯胺和聚苯胺的對稱型超級電容元件，前者表現出最佳的電容特性和在經過500圈後保持超過80%的電容量保留率。
最後，探討在不同電位下，硫醇化聚苯胺對稱型超級電容元件之電致色變特性與電容量之關係，結果顯示當電位增加到1V時，電容量為元件的最大值且處於著色狀態，相對地，當電位下降到-0.2 V時，電容量為最小值且元件處於去色狀態。

Two methods for preparing thiolated polyaniline films were developed using the Thiol-ene click chemistry technique. The electrochemical properties and capacitance of the films were evaluated using cyclic voltammetry. Among these methods, the one involving thiol doping exhibited the best electrochemical characteristics and capacitance, making it suitable for applications in supercapacitor devices. By selecting appropriate substrates, electrolyte compositions and ratios, and thin film deposition on the electrode surface, optimal parameters for the supercapacitor device were determined. A comparison was made between symmetrical supercapacitor devices using thiolated polyaniline and pristine polyaniline under the same parameters, with thiolated polyaniline showing superior capacitance performance and retaining over 80% of its capacitance after 500 cycles.
Finally, the electrochromic properties and capacitance of the symmetrical supercapacitor device using thiolated polyaniline were investigated at different potentials. The results showed that when the potential was increased to 1V, the capacitance reached its maximum value, and the device exhibited a colored state. Conversely, when the potential was decreased to -0.2 V, the capacitance reached its minimum value, and the device exhibited a bleached state.
Overall, the utilization of Thiol-ene click chemistry to prepare thiolated polyaniline thin films demonstrated promising electrochemical properties and capacitance, making it a viable option for advanced supercapacitor applications. The study also highlighted the importance of optimizing parameters and understanding the electrochromic behavior of thiolated polyaniline in different potential ranges for efficient device performance.
