Conductive Polymer Suspension and Method for Manufacturing the Same, Conductive Polymer Material, Electrolytic Capacitor, and Solid Electrolytic Capacitor and Method for Manufacturing the Same

摘要

(assignment) ; conductive polymer to provide a high conductivity of the conductive polymer material service suspension and a method for manufacturing the same, and particularly provides a solid electrolytic capacitor and a manufacturing method of a low ESR. ; (solving means) ; low-molecular-weight organic acid or a salt thereof, or weight from the average molecular weight is less than 2,000 or a water-based solvent having a polyacid dopant consisting of a salt, chemical oxidation polymerization of the monomer giving a conductive polymer by using an oxidizing agent, and producing a conductive polymer suspension. Or, in a low-molecular organic acid or a solvent having a dopant consisting of a salt, a monomer giving a conductive polymer by using an oxidant chemical oxidation polymerization, to synthesize a conductive polymer, the conductive polymer to purified, low molecular weight organic acid or a salt thereof, or from the weight average molecular weight of less than 2000 polyacid or acid component consisting of a water-based solvent with a salt thereof, by mixing the purified conductive polymer and an oxidizing agent, to prepare a conductive polymer suspension.
