聚咯導電膜使用在傳統鋁電解電容器上,代替電解液作為固態電極,所製造的元件有著體積小、容量大而且熱安定性佳和優異的高頻性能等特點,在應用方面逐漸受到重視。本研究即針對單層箔聚咯固態電容器元件之結構設計,以不同鋁箔之導入技術,導電性咯之合成技術以化學氧化合成及電化學合成技術為主。探討表面型態、電性質及熱安定性以建立聚咯固態電容器材料及製程參數之指標,
並以AFM、SEM及EDS分析化成箔表面型態。實驗上,化學含浸法進行4次,導電率可達6×10-1S/cm,電化學法時支持電解質的最佳濃度為0.2M。本研究所製得之固態電容器較傳統的液態電容有更佳的電容效果及安定性。

The Polypyrrole solid electrolyte aluminum capacitor exist low ESR under high frequency and heat resistance for reflow process. The performance of Polypyrrole solid capacitor is influence by the good adhesion of conductive Polypyrrole on the porous aluminum foil. In this study, we emphasize on the process and materials parameter for Polypyrrole film growth on the porous aluminum foil. Through combination of the chemical oxidation and electrochemical synthesis of Polypyrrole on foil and performance evaluation to establish the guidance of ppy solid capacitor process. The forming Aluminum foil were characterized by AFM, SEM and EDS measurement. And chemical immersion of Polypyrrole requires four times to get the conductivity of 6×10-1S/cm. The optimized electrochemical conditions are 2M of the concentration of the Supporting electrolyte. When we test the capacitor made under such conditions, the result is much better and more stable the corresponding values for the liquid aluminum electrolytic capacitor.
