Abstract

See full text

The method for producing an electrically conductive polymer material includes: a preparing step of providing a polymer film formed from an oriented polymeric semiconductor; and a doping step of introducing a first ion into the polymer film, in the doping step, a treatment liquid, which is obtained by dissolving, in an ionic liquid including the first ion having the opposite polarity to carriers to be injected into the polymeric semiconductor by doping in the form of a cation and an anion or an organic solvent having dissolved therein a salt including the first ion, a dopant which has the same polarity as that of the first ion and which oxidizes or reduces the polymeric semiconductor, is allowed to be in contact with the surface of the polymer film to form an intermediate of a second ion formed by ionization of the dopant and the polymeric semiconductor by a redox reaction, and to replace the second ion in the intermediate with the first ion.
