ELECTROCONDUCTIVE POLYMER SUSPENSION AND METHOD FOR PRODUCING THE SAME, ELECTROCONDUCTIVE POLYMER MATERIAL, AND SOLID ELECTROLYTIC CAPACITOR AND METHOD FOR PRODUCING THE SAME |
摘要 |
The present invention provides an electroconductive polymer suspension for providing an electroconductive polymer material with a high electroconductivity and a method for producing the same, and particularly provides a solid electrolytic capacitor with a low ESR and a method for producing the same. It includes a first step of carrying out chemical oxidative polymerization of a monomer providing an electroconductive polymer by using an oxidant in a solvent containing a first dopant including an organic acid or a salt thereof to synthesize an electroconductive polymer; a second step of purifying the electroconductive polymer; a third step of adding a second dopant, mixing an oxidant, subsequently adding a third dopant, and further mixing an oxidant in an aqueous solvent containing the purified electroconductive polymer; and a fourth step of carrying out an ion-exchange treatment to the mixture liquid obtained by the third step to obtain an electroconductive polymer suspension.
