ABSTRACT:
Compositions are provided comprising aqueous dispersions of at least one polypyrrole and at least one colloid-forming polymeric acids at methods of making such compositions. The new compositions are useful in electronic devices including organic electronic devices such as organic light emitting diode displays, memory storage, electromagnetic shielding, electrochromic displays, and thin film transistors, field effect resistance devices.
