Abstract
Electrically conductive polymer compositions are provided. The compositions are dispersed in an aqueous liquid medium having an oxygen content less than 10% of the saturated level. The compositions can be an electrically conductive polymer doped with a fluorinated acid polymer, an electrically conductive polymer in admixture with a fluorinated acid polymer, or mixtures thereof. The conductive polymer composition has a conductivity that changes by less than 10% in 30 days.
