CONDUCTIVE POLYMER COMPOSITION, CONDUCTIVE POLYMER FILM PREPARED FROM THE COMPOSITION AND ORGANIC ELECTRONIC DEVISE USING THE SAME

摘要

A conductive polymer composition, a conductive polymer thin film prepared by using the composition, and an organic electronic device containing the thin film are provided to improve coating property and electrical characteristics. A conductive polymer composition comprises a polythiophene-based conductive polymer aqueous solution; 0.02-5.0 parts by weight of a surface tension controller (surfactant) having both hydrophobicity and hydrophilicity based on the weight of the conductive polymer; and 1-99 parts by weight of a polar solvent. Preferably the polythiophene-based conductive polymer is the poly(3,4-ethylene dioxythiophene) represented by the formula 1 or a mixture of the poly(3,4-ethylene dioxythiophene) represented by the formula 1 and the poly(4-styrene sulfonate) represented by the formula 2, wherein n and m are 5-10,000.
