CONDUCTIVE POLYMER COMPOSITE AND SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a conductive polymer composite which has good filterability and good film formability by spin coating, and can, upon film formation, form a conductive film having high transparency and good flatness.SOLUTION: The conductive polymer composite comprises: a π-conjugated polymer and a dopant polymer containing a repeating unit a represented by a formula (1) and having a weight average molecular weight of 1,000 to 500,000. (Ris H or a methyl group; Ris a single bond, an ether group, an ester group, or a C1-12 linear, branched, or cyclic hydrocarbon group which may have one or both of an ether group and an ester group; Ris a C1-4 linear or branched alkylene group; Z is a phenylene group, a naphthylene group, or an ester group; and a satisfies 0
