SOLID ELECTROLYTIC CAPACITOR WITH HEAT RESISTANT POLYANILINE AND METHOD OF MANUFACTURING THE SAME

摘要

The heat resistant polyaniline or derivative thereof disclosed contains a sulfonic acid compound as a dopant, and the percentage of sulfonic acid groups per recurring unit of the polyaniline or derivative thereof is set to 28 to 40 %. Also, the solid electrolytic capacitor disclosed uses a solid electrolyte of polyaniline or derivative thereof containing a sulfonic acid compound as a dopant, wherein the percentage of sulfonic acid groups per recurring unit of polyaniline or derivative thereof is set to 28 to 40 %. In this selected range of the concentration of the dopant, the conductivity and the pyrolysis commencement temperature characteristics are excellent.
