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 conductive polymer coating formed on a surface, comprising:
- polyethylenedioxythiophene (PEDOT) doped with a plurality of dinonylnapthalenesulfonic acid (DNNSA) anions, the PEDOT having a resistivity of about 100,000 Ohms or less,
- wherein the surface is selected from the group consisting of a metal surface, a carbon allotrope surface, an edge protection layer surface, and a spacecraft surface, wherein the molar ratio of DNNSA to EDOT monomer units is about 1.7.
A composition comprising:
- polyethylenedioxythiophene (PEDOT) doped with a plurality of dinonylnapthalenesulfonic acid (DNNSA) anions, the PEDOT having a resistivity of about 100,000 Ohms or less;
- and
- a resin selected from the group consisting of a polyvinylbutyral, an ethylene-vinyl acetate, a polyimide, a polyolefin, a polyurethane, a silicone, a polyvinylchloride, a nitrile rubber, and combinations thereof, wherein the molar ratio of DNNSA to EDOT monomer units is about 1.7.
