Abstract
Polymerize ethylenedioxythiophene (EDOT) in a polymerization process using dinonylnaphthalenesulfonic acid (DNNSA) as the dopant and Fe(III) p-toluenesulfonate (Fe (III) p-TSA) as the oxidizing agent to produce an organically soluble polyethylenedioxythiophene (PEDOT).
Claims20
A method of forming a conductive polymer coating over a substrate, comprising:
- synthesizing polyethylenedioxythiophene (PEDOT) doped with anions by introducing ethylenedioxythiophene (EDOT) monomers with a transition-metal p-toluenesulfonic acid in an organic solvent having a dipole moment of less than 1.5;
- dissolving the PEDOT doped with the anions and a binder resin in the organic solvent to form a conductive polymer coating composition;
- applying the conductive polymer coating composition over the substrate to form the conductive polymer coating;
- and
- drying the conductive polymer coating at a temperature less than 100° C. for a time period of at least one hour.
