Sulfonic acid-substituted polyaniline salt compositions, processes for their preparation and uses therefor are disclosed. The sulfonated polyaniline salt compositions have fast electronic and optical responses to electrochemical potentials, improved environmental stability, and improved solubility.
Sulfonic acid-substituted polyaniline salt compositions, processes for their preparation and uses therefor are disclosed. The sulfonated polyaniline salt compositions have fast electronic and optical responses to electrochemical potentials, improved environmental stability, and improved solubility. A process for producing the sulfonated polyaniline salt compositions comprises reacting a sulfonated polyaniline polymer with an aqueous basic solution. The sulfonated polyaniline compositions are useful for absorption of electromagnetic radiation, as a high density erasable data storage medium for use in information storage and processing applications, and to provide electronic, chemical, electrochemical, and optical microelectronic devices which use and control the chemical and physical properties of the sulfonated polyaniline salt compositions.
