Abstract
Provided are a conductive polymer composite and composition which: improve water volatilization efficiency during film formation by incorporating a novel non-doping fluorinated unit in a dopant polymer; also reduce Hgeneration by using the non-doping fluorinated unit in place of an acid unit generating extra acids; have good filterability and film formability; and are capable of forming a film having high transparency and good flatness when the film is formed. The conductive polymer composite is a composite containing: (A) a π-conjugated polymer; and (B) a dopant polymer which is a copolymer containing a repeating unit 'a' shown by the following general formula (1) and at least one repeating unit 'b' selected from repeating units shown by the following general formulae (2-1) to (2-7).
