Abstract

가용성 전도성 고분자를 포함하는 폴리피롤복합막을 고체전해질층으로 하는 알루미늄 고체전해 콘덴서를 제조하기 위하여 가용성 전도성 폴리헥실치오펜을 합성하고, 상기 가용성 전도성 고분자를 용액함침법에 의해 산화알루미늄막 상부에 전그층으로 형성한 후, 전해산화중합시의 양극으로 이용하여 고전도성을 갖는 폴리피를 고체전해질층을 형성시켜 알루미늄 고체전해 콘덴서를 제조한다.To prepare an aluminum solid electrolytic capacitor using a polypyrrole composite film containing a soluble conductive polymer as a solid electrolyte layer, a soluble conductive polyhexylthiophene was synthesized, and the soluble conductive polymer was used as a solution layer on the aluminum oxide layer by solution impregnation. After forming, the polypy having high conductivity is formed as a positive electrode during electrolytic oxidation polymerization to form a solid electrolyte layer, thereby producing an aluminum solid electrolytic capacitor.
