Abstract : The research towards this endeavor started with the development of a new conductive polymer compound, a double strand complex of polyaniline with a full range of different polyelectrolytes. This new compound is in the form of a twisted double helix, similar to DNA. The drive for this development was to improve the stability of the electroactive green colored form of polyaniline under heat, solvents and pH environments and improve the solubility characteristics of the polymer. The goal of this work is to try to increase the pKa of the polyaniline strand. The other approach is to blend the conductive double strand complexes with various epoxies to slow down the de-protonation process of the polyaniline. This work could lead to a new primerless epoxy coating technology.
