  • Conductivity enhancement of conductive polymers by solvent exposure
    Publication number: 20070085061
    Abstract: The electrical conductivity of thin films of transparent conducting polymers such as poly(3,4-ethylenedioxythiophene)/polystyrene sulfonic acid (PEDOT/PSS) can be increased greatly by exposure to certain polar organic solvents, aqueous/organic solutions, and aqueous/organic or organic solutions containing additives such as oxidative dopants, monomers, organic compounds, or combinations thereof. The transparency of the film in the visible region of the spectrum is maintained after treatment to enhance conductivity. The conductivity of films of transparent conducting polymers based on poly(thienothiophenes) such as poly(thieno[3,4-b]thiophene)/PSS (PTT/PSS) and poly(thieno[3,4-b]thiophene)/fluoropolymeric acid is altered to much less of a degree by analogous solvent treatment, or by direct solvent addition into PTT dispersions.
