ABSTRACT:
A method for increasing the conductivity of a composition of a polyaniline salt of an organic acid is disclosed. The method comprises contacting the composition with a polar organic solvent that is capable of solubilizing the organic acid without solubilizing the polyaniline salt. Also provided are coating compositions which can be prepared by the method.
