Problems solved by technology

However, this method suffers from the disadvantage of not being able to remove cations firmly attached to the surface of intrinsically conductive polymers.
Poor dispersion stability of intrinsically conductive polymers in organic solvents due to remaining cations
And it shows that it is difficult to reduce the water content below 1 wt% (see Patent Document 4)

Abstract

Disclosed is a conductive coating composition containing an organic solvent dispersion of an intrinsically conductive polymer such as a doped polyaniline or a doped polythiophene, and a binder. The conductive coating composition is characterized in that the binder contains a polymerizable monomer-dispersed silica sol, which is obtained by dispersing a colloidal silica into a polymerizable organic compound monomer. The composition provides a conductive thin film having high transparency and excellent strength.

Description

technical field [0001] The present invention relates to conductive coating compositions, and more particularly, to conductive coating compositions comprising a dispersion of an inherently conductive polymer in an organic solvent and a binder. Background technique [0002] For aromatic conductive polymers such as polyaniline, polythiophene and polypyrrole, there is a growing expectation for new uses due to their remarkable stability and conductivity. [0003] Unfortunately, these conductive polymers are not soluble in any solvents and thus have poor moldability. Therefore, they are limited in their fields of application. [0004] In recent years, it has been reported that improvement in moldability is possible if a conductive polymer in the form of fine particles is dispersed in water or an organic solvent such as an aromatic solvent (see Patent Documents 1 and 2). [0005] The above conductive polymers are made into dispersions of intrinsically conductive polymers by combi...
