Title:
METHOD FOR PRODUCTION OF SOLID ELECTROLYTE AND SOLID ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2007/069738
Kind Code:
A1
Abstract:
Disclosed is a method for production of a solid electrolyte composed of a conductive
polymer by applying a solution containing a 5-membered heterocyclic compound
as a polymerizable monomer onto the surface of a substrate to polymerize the monomer.
In the method, as the solution containing the monomer, a solution containing
the monomer and at least one selected from a dimer and a trimer of the monomer at
a ratio satisfying the requirement indicated by the formula below onto the surface
of a substrate to polymerize the monomer: (concentration of monomer)/(concentration
of dimer of the monomer in monomer terms + concentration of trimer of the monomer
in monomer terms) = 100-1,000,000. Alternatively, a solution of a compound having
a thiophene skeleton and having an absorbance of 1.5 to 10 as measured at a wavelength
of 300 to 340 nm may be applied onto the surface of a substrate to polymerize the
compound. The solid electrolyte produced by the method is useful as a solid electrolytic
capacitor element.
