Abstract
Provided are compositions having high conductivity and high work-function. The compositions comprise an aqueous dispersion or solution of an electrically conducting polymer and a perfluorinated polymeric acid. The conductive polymers may be made from conjugated monomers or comonomers and a non-fluorinated polymeric acid, and the perfluorinated polymeric acides may be derived from perfluoroolefins having perfluoro-ether-sulfonic acid side chains. Devices embodying such compositions are also provided.
