ABSTRACT:
A process for producing a conductive polyaniline is disclosed. The process includes mixing an aniline monomer, a water-immiscible organic solvent, at least one protonic acid doping agent and water together to form an emulsion via agitation, stopping agitation to allow the emulsion to separate into an aqueous phase and a non-aqueous phase, separating the non-aqueous phase from the aqueous phase, and adding an oxidation agent into the non-aqueous phase to carry out polymerization. A non-aqueous in-situ formed transparent polyaniline solution prepared by the process is also disclosed.
