Abstract
The present invention relates to electrically conductive polymer compositions, and their use in electronic devices. The compositions contain a semi-aqueous dispersion of at least one electrically conductive polymer doped with at least one highly-fluorinated acid polymer, non-conductive oxide nanoparticles, at least one high-boiling organic liquid, and at least one lower-boiling organic liquid.
