| abstract |
Compositions comprising an aqueous dispersion of polyaniline and a colloid-forming polymeric acid are provided. Films from the compositions of the present invention are useful as buffer layers in organic electronic devices, including electroluminescent devices such as organic light emitting diode (OLED) displays. Films cast from the compositions of the present invention are also useful in applications such as the drain, source or gate electrodes of thin film field effect transistors in combination with metal metal wires or carbon nanotubes. |
