Claims
- 1. An electrically conductive shaped article formed from a blend comprising a Lewis base electrically conductive polymer material selected from the group consisting of substituted and unsubstituted polyparaphenylenevinylenes, polyanilines, polyazines, polythiophenes, poly-p-phenylene sulfides, polyfuranes, polypyrroles, polyselenophenes, polyacetylenes, formed from soluble precursors and combinations and blends thereof, compounded and blended at a molecular scale with a dielectric Lewis acid polymer dopant, selected from the group consisting of, cellulose sulfonic acid, polyamic acid, polyphosphoric acid, polymers containing acid chloride (—CO—Cl) and polymers containing sulfonyl chloride groups, said Lewis acid polymer dopant dopes said Lewis base electrically conductive polymeric undoped form to obtain said electrically conductive blend formed into said shaped article.
- 2. The shaped article defined in claim 1, wherein said electrically conductive polymer material is in the form of a fiber.
- 3. The shaped article defined in claim 1, wherein the form of said article is an electrically conductive body selected from the group consisting of a crystalline solid, an amorphous solid, a polycrystalline solid, a semi crystalline solid and glass.
- 4. The shaped article defined in claim 1 that has been shaped into a stylus suitable for use in resistive film digitizer.
