摘要

本研究探討以聚苯胺導電高分子填充鋁膠多孔電極，使電極的
鋁顆粒被聚苯胺薄層所包覆，形成複合結構，此結構可提升電極導電

度的提升、電池光電轉換效率的變化以及環境耐受度的測試。
在聚合實驗中，選擇乳化劑與摻雜酸作為操縱參數，討論乳化
劑與摻雜酸的選擇對產物熱穩定性與導電性的影響，以及它們在聚合
反應中扮演的角色。鋁膠電極的導電性會因為聚苯胺的塗佈而改變，
本研究以電性量測結果配合電子傳遞的可能機制，確認聚苯胺填充的
相關參數對此複合電極電性的影響，並由此討論提高導電性的可行
性。填充聚苯胺後電池光電轉換效率的變化，主要藉由分析電池的
串、並聯電阻，確認聚苯胺包覆層對電池相關參數的影響，本研究發
現此處理可使電池效率提升約0.66 %。最後，為確認此處理對鋁膠電
極環境耐受度的影響，本研究利用水熱處理與腐蝕實驗分別測試此複
合電極的抗氧化能力與抗腐蝕能力。

This study investigated the influence of conducting polymer
polyaniline on the electric properties of the porous aluminum paste
electrode. After the filling treatment, the aluminum particles of the porous
aluminum paste electrode were covered by a thin layer of PAni. The
formation of composite electrode structure leads to increase of electric
conductivity of electrode, cell efficiency, and endurance level of the cell
were investigated in depth.
In the PAni synthesis experiment, the effects of the dispersant and
the doping acid on the thermal stability and the conductivity of the
products were studied. In the electric conductivity, the effects of PAni
coating on the conductivity of the composite electrode can be explained
by the electron transport mechanism. In the cell efficiency experiment,
the effects of the presence of the PAni coating layers on the cell
efficiency were attributed to the series and shunt resistance. In the
endurance experiment, the hydrothermal and the corrosion tests were
adopted to study the anti-oxidative and the anti-corrosive capacities
individually.
Based on this study, the conductivity of the electrode was enhanced
which is attributed to both the improvement of the electric properties of
PAni and the formation of the composite electrode structure. Thus the cell
efficiency and the endurance level were improved, and the highest
increment of the cell efficiency in this study was 0.66 %.
