<p>Optically transparent, conductive polymer compositions and methods for ma king them are claimed. These conductive polymer compositions comprise an oxi dized 3,4- ethylenedioxythiopene polymer, a polysulfonated styrene polymer, single wall carbon nanotubes and/or metallic nanoparticles. The conductive p olymer compositions can include both single wall carbon nanotubes and metall ic nanoparticles. The conductive polymer compositions have a sheet resistanc e of less than about 200 Ohms/square, a conductivity of greater than about 3 00 siemens/cm, and a visible light (380-800 nm) transmission level of greate r than about 50%, preferably greater than about 85% and most preferably grea ter than about 90% (when corrected for substrate). The conductive polymer co mpositions comprising single wall carbon nanotubes are made by mixing the ox idized 3,4-ethylenedioxythiopene polymer and polysulfonated styrene polymer with single wall carbon nanotubes and then sonicating the mixture. The condu ctive polymer compositions comprising metallic nanoparticles are made by a p rocess of in situ chemical reduction of metal precursor salts.</p> |
