Abstract

Disclosed is an electrically conductive polymer composition comprising a dopant and a p-conjugated polymer, which can be uniformly dissolved in a solvent and form a smooth film. Specifically disclosed is an electrically conductive polymer composition comprising a polymer compound (A) and a p-conjugated polymer (ss), wherein said polymer compound (A) is obtained by polymerizing 10-50 mol% of a monomer (a-1) having a sulfonic acid group or a sulfonate group, 10-90 mol% of a monomer (a-2) having a chelating ability and 0-70 mol% of another monomer (a-3), and said p-conjugated polymer (ss) is obtained by polymerizing at least one kind of a monomer selected from among monomers represented by formulae (I) to (III).

Description

technical field [0001] The invention relates to a conductive polymer composition and a preparation method thereof. More specifically, it relates to a conductive polymer composition containing a π-conjugated polymer and a preparation method thereof. Background technique [0002] In order to impart higher conductivity to the π-conjugated polymer, doping with a dopant is performed. [0003] However, in a polymer originally developed in π-conjugation, the planarity of the polymer chain is high, and the crystallinity (stacking property) between the polymer chains due to the affinity of the π bond is high. When such a π-conjugated polymer is doped with a dopant, the above-mentioned planarity and crystallinity will be further improved. Therefore, the solubility (solubility by heat or solvent) of the π-conjugated polymer doped with the dopant generally decreases. [0004] Therefore, it is known that it is difficult to achieve both high electrical conductivity and high solubility ...
