Abstract:
A conductive polymer composition having a conductivity of at least about 10.sup.-12 Siemens/cm (S/cm) and comprising an intrinsically-conductive polymer which is doped with at least two different dopants, including a first dopant having a molecular weight of less than about 1,000 and a second dopant which is polymeric and has a weight average molecular weight of greater than about 2,000, wherein the first dopant is dodecylbenzenesulfonic acid, para-toluenesulfonic acid or hydroxybenzenesulfonic acid, and wherein the first dopant is present in an amount sufficient to increase the conductivity of the composition, relative to the conductivity of a composition, which is the same in all respects, except that the intrinsically-conductive polymer has the same molar amount of available sites doped solely with the second dopant.
