Abstract
The present invention provides a formulation for forming an electronically conducting polymer. The formulation contains an electron acceptor comprising a dopant anion and a metal cation selected from Ag.sup.+, Fe.sup.3+, Cu.sup.2+ or combinations thereof. The preferred electron acceptor is a silver salt, preferably selected from AgNO.sub.3, AgClO.sub.4 and AgNO.sub.2. The formulation also contains between 2 and 100 moles of a polymerizable component per mole of the electron acceptor, the polymerizable component being selected from pyrrole, aniline, their oligomers, or combinations thereof. In addition, the formulation includes an aqueous solvent selected from acetonitrile, acetone, and combinations thereof, the aqueous solvent having up to 30 volume percent water.
