Conductive polymer compositions and method for the production thereof.

In a soln. of an inherently conductive polymer (such as polyaniline or polythiophene) in a polar solvent, the polymer is doped with a sulfonated polymer contg. arom. repeating units which form a rigid or semi-rigid backbone, the sulfonated polymer contg. a sufficient amt. of free sulfonic groups to maintain the complex in soln. The sulfonated polymer forms a doped, conductive complex with a polymer comprising a conjugated polymeric chain and it contains a sufficient amt. of free sulfonic groups to maintain the complex in soln. The novel solns. can be used for producing conductive films, for coating various substrates and for producing elec. conductive ink formulations for printed electronics applications. [on SciFinder(R)]
