| 摘要 |
Methods are provided for directly producing a stable aqueous dispersion of an electrically conducting polyaniline, comprising synthesizing an electrically conducting polyaniline in the presence of a polymeric acid in aqueous solution, thereby forming an as-synthesized aqueous dispersion comprising the electrically conducting polyaniline and the polymeric acid, and contacting the as-synthesized aqueous dispersion with at least one ion exchange resin under conditions suitable to produce a stable aqueous dispersion of an electrically conducting polyaniline. Aqueous dispersions produced by the methods of the invention are useful for preparing buffer layers for use in electroluminescent (EL) devices. |
