Compositions are provided comprising aqueous dispersions of polythiophenes a nd colloid-forming polymeric acids. Films from invention compositions are usefu l as buffer layers in organic electronic devices, including electroluminescent devices, such as, for example, organic light emitting diodes (OLED) displays in combination with metal nanowires or carbon nanotubes in applications such as drain, source, or gate electrodes in thin film field effect transistors.< /SDOAB> |
