Water-dispersible electrically conductive fluorine-containing polyaniline compositions for lithography |
| 摘要 |
A water dispersible composition comprises a polyaniline copolymer having a weight average molecular weight of at least 30,000 and a polymeric acid comprising sulfonic acid groups. The polyaniline copolymer comprises i) about 10 mol % to about 15 mol % of a fluorine-containing first aniline repeat unit based on total moles of repeat units in the polyaniline copolymer, and ii) a second aniline repeat unit comprising no fluorine. The sulfonic acid groups of the polymeric acid are present in a molar amount greater than or equal to total moles of repeat units of the polyaniline copolymer. The composition has a conductivity of at least 0.0001 S/cm. |
