CONDUCTIVE POLYMER COMPOSITION AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A conductive composition is provided to improve crosslink density and to have excellent electric conductivity and stability by adding a polycellulose sulfonate into poly(3,4-ethylenedioxythiophene), as a dopant. CONSTITUTION: A conductive composition comprises 0.1-50 parts by weight of a conductive polymer which is doped with polycellulose sulfonate, and has one or more sulfonate groups in a copolymer as a random copolymer having a unit structure indicated in chemical formula 1; and 50-99.9 parts by weight of a solvent. R is selected from -H, -(CH2CH2)-OH, -CH2CH2OCH2CH(OH)CH2SO3H, and -CH2CH2OCH2CH(OH) CH2O-mC18H37; and m is 1 or more.
