ELECTROCONDUCTIVE POLYMER COMPOSITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To obtain an electroconductive polymer composite material excellent in processability and mechanical properties without requiring any electroconducting treatment such as an (electric) or chemical doping by including a specific self-doping type electroconductive polymer and an N-vinitycarboxylic amide-based polymer. SOLUTION: This composite material is composed of (A) a self-doping type electroconductive polymer such as poly(5-sulfoisothianaphtene-1,3-diyl) containing a Broensted acid group such as sulfonic acid (sulfonate) group having a dopant ability in a molecule and (B) an N-vinylcarboxylic amide-based polymer containing a copolymer structure with acrylic acid (or alkali metal salt). Preferably, a self-doping type elecroconductive polymer composite thin film is produced by applying a solution of the electroconductive polymer composite material on the surface of a substrate.
