An electrically conducting film according to the present invention is deposited by immersing the electrode in a solution of a precursor polymer in a predetermined solvent. The precursor polymer includes a plurality of electrochemical polymerizable monomers. Each monomer has first and second polymer-forming active sites that can be joined by electrochemical polymerization and third and fourth polymer-forming active sites that can be joined chemically in solution. The precursor polymer is constructed from the monomers joined by the third and fourth polymer-forming active sites. The precursor polymer is soluble in the solvent whereas a polymer formed by electrochemical polymerization of the first and second polymer-forming active sites is insoluble in the solvent. | InventorsApplicationNo. 401666 filed on 09/22/1999US Classes:428/212, Including components having same physical characteristic in differing degree205/50, PRODUCT PRODUCED BY ELECTROLYSIS INVOLVING ELECTROLYTIC MARKING, BATTERY ELECTRODE ACTIVE MATERIAL FORMING, ELECTROFORMING, OR ELECTROLYTIC COATING428/220, Physical dimension specified526/173, Material contains elemental alkali metal, hydride thereof, or alkali metal to carbon atom bond (Li, Na, K, Rb, Cs, Fr)526/256, From monomer containing sulfur atom as part of a heterocyclic ring528/379, Material contains a Group IA (Li, Na, K, Rb, Cs, Fr) or Group IIA metal atom (Be, Mg, Ca, Sr, Ba, Ra)528/392, POLYMER OF AN ETHYLENICALLY UNSATURATED REACTANT WITH A SATURATED REACTANT528/396, FROM HYDROCARBON REACTANT528/397, FROM HALOGENATED HYDROCARBON REACTANT528/482, Contacting with ion exchange material or solid sorbent528/490, Contacting with specified element or with specified inorganic compound other than water, elemental nitrogen, air and the inert gases (Group VIII A)528/492Nitrogen containingField of Search205/50, PRODUCT PRODUCED BY ELECTROLYSIS INVOLVING ELECTROLYTIC MARKING, BATTERY ELECTRODE ACTIVE MATERIAL FORMING, ELECTROFORMING, OR ELECTROLYTIC COATING428/212, Including components having same physical characteristic in differing degree428/220, Physical dimension specified528/490, Contacting with specified element or with specified inorganic compound other than water, elemental nitrogen, air and the inert gases (Group VIII A)528/492, Nitrogen containing528/396, FROM HYDROCARBON REACTANT528/482, Contacting with ion exchange material or solid sorbent528/379, Material contains a Group IA (Li, Na, K, Rb, Cs, Fr) or Group IIA metal atom (Be, Mg, Ca, Sr, Ba, Ra)528/392, POLYMER OF AN ETHYLENICALLY UNSATURATED REACTANT WITH A SATURATED REACTANT528/397, FROM HALOGENATED HYDROCARBON REACTANT526/173, Material contains elemental alkali metal, hydride thereof, or alkali metal to carbon atom bond (Li, Na, K, Rb, Cs, Fr)526/256From monomer containing sulfur atom as part of a heterocyclic ringExaminersPrimary: Wong, DonUS Patent References4599194, Simultaneous polymerization, doping and solubilization of heterocyclic polymers, solutions and cast articlesIssued on: 07/08/1986 Inventor: Frommer , et al.5900327Polyfluorenes as materials for photoluminescence and electroluminescence Issued on: 05/04/1999 Inventor: Pei, et al.
