Patent ID: 6967236

Claim:
A method comprising: providing a solvent and a conjugated polymer system; mixing said polymer comprising said polymer system with said solvent to form a solution; said polymer is selected from the group consisting of a precursor to an electrically conductive polymer and an electrically conductive polymer; in the event said polymer is a precursor to an electrically conductive polymer, said precursor to said electrically conductive polymer being made conductive by adding a dopant to said precursor to an electrically conductive polymer; said solvent comprising a combination of a fluorinated polar solvent, and a nonfluorinated solvent; said polymer in said solution characterized by a dependence of the electrical conductivity of said electrically conductive polymer and said precursor, when converted to said electrically conductive polymer, on the concentration of said polymer in said solution, selecting said concentration to substantially maximize said electrical conductivity; processing said solution to form an article.
