摘要:
An aqueous dispersion used for producing a conductive film is provided. The dispersion contains a complex of poly(3,4-dialkoxythiophene) and a polyanion, and is produced by polymerizing 3,4-dialkoxythiophene in an aqueous solvent in the presence of the polyanion by using peroxodisulfuric acid as an oxidizing agent or by using an oxidizing agent and an acid that is employed so as to lower pH of the reaction mixture.

摘要:
The present invention provides a method for the production of an aqueous dispersion containing an electroconductive polymer component which enables electroconductive thin films which are outstanding in their transparency and electroconductivity to be formed, together with the aqueous dispersion obtained by said method. This method includes a stage in which a 3,4-dialkoxythiophene is polymerized in an aqueous solvent using an oxidizing agent in the presence of a polyanion and, in this stage, said oxidizing agent is added by the dropwise addition of a solution or dispersion containing said oxidizing agent to the reaction solution or, alternatively, in the polymerization stage, the alkali metal ion concentration in the reaction liquid is maintained at no more than 400 ppm.
