COMPOSITION CONTAINING PEDOT:DEXTRAN COPOLYMER AND ITS MANUFACTURING METHOD

摘要

PURPOSE: A composition which comprises a poly(3,4-ethylenedioxythiophene)-dextran copolymer is provided to be easily dispersed into an aqueous solvent by low mixing ratio of dextran sulfate to poly(3,4-ethylenedioxytiophene). CONSTITUTION: A composition which comprises a poly(3,4-ethylenedioxythiophene)-dextran copolymer is obtained by applying dextran sulfate indicated in chemical formula 4 as a polyanion into 3,4-ethylenedioxythiophene indicated in chemical formula 1 under an H2O solvent, oxidative polymerization of the outcome by an oxidant, and treating the reaction mixture by the oxidative polymerization through an ion exchange resin. The weight of the poly(3,4-ethylenedioxythiophene)-dextran copolymer is 1-4 weight%.
