Interest has been shown in double-strand (d-s) polyanilines by many researchers, because they offer fairly good stability under cycles of heat, water, or solvents [326-329] compared to traditional single-strand (s-s) polyanilines. These double-strand polyaniline complexes may be soluble in water or organic solvents, be sus-pendable as latex, or show strong adhesion with metals and polymers. The d-s polyanilines do not unwind or decompose in acids, bases, solvents, mild oxidant-reductants, or heat in contrast to s-s polyanilines, because s-s polyanilines lose dopant and become nonconductive under such conditions. DSC data confirm that this material is a molecular complex and not a simple blend of two components [326].
