Résumé en anglais

Inorganic transparent conductive oxides have dominated the market as transparent electrodes due to theirhigh conductivity and transparency. Here, we report the fabrication and optimization of the synthesis ofpoly(3,4-ethylenedioxythiophene) trifluoromethanesulfonate via vapor phase polymerization for thepotential replacement of such inorganic materials. The parameters and conditions of the polymerizationwere investigated and an electrical conductivity of 3800 S cm1 and 4500 S cm1 after acid treatmentwere obtained while maintaining an absorbance similar to that of commercial indium tin oxide. Thisincrease in electrical conductivity was rationalized experimentally and theoretically to an increase in theoxidation level and a higher order of crystallinity which does not disrupt the p–p stacking of PEDOT chains.< Réduire
