- Doping with a dopant is essential for imparting high conductivity in a ⁇ -conjugated polymer.
- a polymer in which ⁇ conjugation has originally developed has a structure in which the polymer chain has high planarity and crystallinity (stacking property) between polymer chains due to the affinity of ⁇ bond.
- the ⁇ -conjugated polymer doped with the dopant has higher planarity and higher affinity due to ⁇ -conjugation, and the stacking property becomes more remarkable. For this reason, it is a difficult problem to achieve both the dissolution (by heat or solvent) of the ⁇ -conjugated polymer and the electrical conductivity.
- Patent Document 1 a polymer in which an alkyl group, an alkoxy group, or the like is introduced into the side chain of the ⁇ -conjugated polymer has been proposed.
- Patent Document 1 In order to increase the electrical conductivity up to, doping is necessary. When this doping is performed, as a result, there is a problem that sufficient solvent solubility cannot be obtained due to the development of the planarity of the conductive polymer and the development of ⁇ -conjugate affinity.
- conductive polymers When considering the use of conductive polymers, from the viewpoint of ease of handling, it is possible to dissolve by a solvent or melt by heat, and after forming a film, a self-supporting film or a self-supporting body having sufficient electrical conductivity is required.
- a polymer film is formed by electrolytic polymerization or vapor exposure on a substrate to which direct conductivity is desired, an oxidizing agent and a conductive polymer. After being immersed in the precursor monomer solution, a thin film polymerization or the like is performed by heating or the like, and then the resulting polymer film is doped.
- the electrolytic polymerization requires the substrate to be a semiconductor or a conductor, and corrosion resistance to the electrolytic solution is also required, so that usable substrates are limited.
- the oxidant homogeneously present in the thin film that becomes the polymerization field, which is not sufficient in terms of film formation control.
- fine irregularities were formed, and it was difficult to form a conductive polymer on a sufficiently homogeneous surface.

- PSS polystyrene sulfonic acid
- the PEDOT / PSS obtained here is dispersed in water, it is not completely dissolved, it is difficult to suppress stacking between partial PEDOTs, and it is difficult to dissolve the conductive polymer. It was enough.
- the sulfonic acid group can originally exhibit an effect as a dopant group or a water-soluble functional group. This is because it has no substantial affinity or compatibility with the monomer monomer, and it is important to use an alkoxyl group-containing aromatic or heterocyclic compound in the monomer structure. This is because it does not have a compatibilizing functional group with an alkoxyl group for controlling localization and sufficiently inhibiting the planarity of the ⁇ -conjugated polymer.

- Patent Document 11 discloses an antistatic film in which an antistatic material containing a polythiophene compound, an acidic polymer, and a sugar alcohol is applied to a thermoplastic resin film.
- the antistatic film obtained has good transparency and antistatic properties, but polystyrene sulfonic acid is used as a doping agent for polythiophene compounds. Since only an acidic polymer such as the above is used, the antistatic film absorbs moisture over time, and there is a problem that adhesion and antistatic properties are lowered.
- the present invention provides a conductive polymer composition that is excellent in solubility in a solvent and is a self-supporting film, that is, a homogeneous film or molded body that does not cause pinholes alone, a method for producing the same, and the like. It is an issue.
