Abstract
There is provided an oxidant and dopant which can produce a conductive polymer. The conductive polymer can be used in a solid electrolyte capacitor as solid electrolyte. The solid electrolyte capacitor can be provided with improved breakdown voltage and voltage resistance, as well as less generation of the defects due to leak current. There is provided an oxidant and dopant solution for conductive polymer production including an oxidant and dopant for an organic ferric sulfonate, and an alcohol with a carbon number of 1 to 4. The oxidant and dopant solution further includes a compound with a glycidyl group, or its ring-opened compound. Faborably, a polyalcohol is further added. Using the oxidant and dopant solution, a thiophene or its derivative is subject to an oxidation polymerization to prepare a conductive polymer, which can be used as solid electrolyte of a solid electrolyte capacitor.
