Abstract
Polymeric compositions are disclosed comprising protonated, electrically conducting polyaniline; cyclic organic compounds capable of forming ring-ring interactions with the six-membered rings of the polyaniline and hydrogen bonding with the NH groups of the polyaniline; and anionic surface active additives. According to the invention, no particular requirements are posed for the counter-ions of polyaniline, which allows for the use of non-functionilized counter-ions. The conducting polyaniline complexes of the invention are processible in the fluid-phase and exhibit significantly improved electrical properties.
