Claim 3:
4. A method for preparing an alcohol dispersion of a conductive polyethylenedioxythiophene of claim 1, comprising:
providing a fluorinated sulfonic acid ionomer and 3,4-ethylenedioxythiophene monomer comprising an R-group side chain, wherein the R-group side chain is a hydrogen atom, hydroxyl, alkyl, alkoxy, fluoroalkyl, ester group, carboxyl, thioalkyl, aryl, or heteroaryl;
adding the fluorinated sulfonic acid ionomer and 3,4-ethylenedioxythiophene monomer in a solvent to prepare a dispersion with a mass concentration of 1% to 30%;
adding an oxidant to the dispersion for reaction to obtain a blue-black liquid; and
removing the unreacted monomer and oxidant from the blue-black liquid by dialysis through a semi-permeable membrane, followed by centrifugal separation, to obtain a blue-black solid;
adding the blue-black solid to an alcohol solution, and processing the blue-black solid and the alcohol solution by ultrasonic cell pulverization to obtain the alcohol dispersion of the conductive polyethylenedioxythiophene according to claim 1,
wherein the alcohol solution is one or a mixture of two or more of an aliphatic alcohol solution, an alicyclic alcohol solution, and an aromatic alcohol solution.
