Abstract
Multicomponent polymeric compositions comprising self-prontonated sulfonic acid-substituted polyaniline compositions or derivatives thereof and at least one insulating polymer are disclosed. The sulfonated polyaniline compositions have faster electronic and optical responses to electrochemical potentials, improved environmental stability, and improved solubility than the parent polymer, polyaniline. The multicomponent sulfonated polyaniline/insulating polymer compositions are useful in electronic, chemical, electrochemical, and optical microelectric applications which use and control the chemical and physical properties of the sulfonated polyaniline compositions.
