Abstract
Abstract Sulfonic acid-substituted polyaniline salt compositions 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. The sulfonated polyaniline salt compositions are useful as an ionic electrolyte polymer.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
226 words
An ionic polymer electrolyte comprising a self-doped, sulfonated polyaniline salt composition having a chemical composition of formula I ##STR8## wherein O≦y≦1, R 1 , R 2 , R 3 , R 4 , R 5 and R 6 are independently selected from the group consisting of H, --SO 3 H, --R 7 SO 3 H, --SO 3 M, --R 7 SO 3 M, --OCH 3 , --CH 3 , --C 2 H 5 , --F, --Cl, --Br, --I, --N(R 7 ) 2 , --NHCOR 7 , --OH, --O - , SR 7 , --OR 7 , --OCOR 7 , --NO 2 , --COOH, --COOR 7 , --COR 7 , --CHO and --CN, wherein R 7 is a C 1 -C 8 alkyl, aryl or aralkyl group, wherein M is a positive cation; the sulfonated polyaniline composition being comprised of x and z fractions of phenyl or quinoid rings, wherein x is that fraction of phenyl or quinoid rings that have an --SO 3 - group and wherein z is that fraction of phenyl or quinoid rings that have an --SO 3 .sup. - group and the M positive cation; such that when the sulfonated polyaniline composition has fewer z fractions than x fractions, the composition is an electrical conductor and as the number of z fractions approaches the number of x fractions, the composition becomes nonconducting.
Claim 2
Dependent Claim
