Compositions are provided comprising aqueous dispersions of polyaniline and colloid-forming polymeric acids. Films from invention compositions are useful as buffer layers, in organic electronic devices including electroluminescent devices, such as organic light emitting diodes (OLED) displays. Films cast from invention compositions are also useful in combination with metal metalwires or carbon nanotubes in applications such as drain, source, or gate electrodes in thin film field effect transistors.
L'invention concerne des compositions comprenant des dispersions aqueuses de polyaniline et d'acides polymères formant une matière colloïdale. Les films obtenus à partir des compositions de l'invention sont utiles en tant que couches tampons, dans des dispositifs électroniques organiques comprenant des dispositifs électroluminescents, de type affichages à diodes électroluminescentes organiques (OLED). Les films coulés à partir des compositions de l'invention sont également utiles en combinaison avec des fils métalliques ou des nanotubes de carbone dans des applications de type électrode de source, de drain ou de grille dans des transistors à effet de champ à couche mince.
