Compositions are provided comprising aqueous dispersions of polythiophenes and colloid-forming polymeric acids. Films from invention compositions are useful 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.
La présente invention concerne des compositions qui comprennent des dispersions aqueuses de polythiophènes et des acides polymères formant des matières colloïdales. Des films issus des compositions de l'invention conviennent comme couche tampon dans des dispositifs électroniques organiques, notamment des dispositif électroluminescents tels que, par exemple, des diodes électroluminescentes organiques combinées avec des nanocâbles métalliques ou des nanotubes de carbone dans des applications telles que des électrodes de drain, de source ou de grille dans des transistors à effets de champs à film mince.
