ABSTRACT:
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.
