Self-protonating sulfonic acid-substituted polyaniline compositions, methods of preparation and uses thereof. The sulfonated polyaniline compositions are useful in the conduction of electricity, the absorption of electromagnetic radiation, the modulation of electromagnetic beams and the modification of the electromagnetic response of sulfonated polyaniline compositions using chemical or electrochemical means. The sulfonated polyaniline compositions are also useful as a high density erasable data storage medium, used in information storage and in processing applications. The sulfonated polyaniline compositions make it possible to obtain electronic, chemical, electrochemical and optionally micro-electronic devices, which use and regulate the chemical and physical properties of the compositions. |
