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.

摘要:
The present invention provides a conductive resin composition that comprises a complex of poly(3,4-dialkoxythiophene) and a polyanion, wherein the complex has a conductivity of 0.30 S/cm or more. This composition is preferably used for production of a conductive film having a conducting layer made of the composition, and the resulting conductive film is preferably used in a resistive-type film switch.
