NOVELTY - The conductive film comprises a network of copper nanowires, a supportive material consisting of cellulose materials, glues, polymeric materials and overcoat materials, and a protective film over the copper nanowires. The conductive film has a sheet resistance of less than 10000 Omega /sq and a transparency of greater than 60%. The copper nanowires comprise a copper stick attached to a spherical copper nanoparticle. The copper stick has a first end and a second end, a length of 1-500 microns, and a diameter of 20-300 nm. The spherical copper nanoparticle has a diameter of 30-1000 nm.    USE - The conductive film is useful for low- emissivity windows, flat-panel displays, touch-sensitive control panels and solar cells.    ADVANTAGE - The conductive film is efficient and economical to manufacture, and has high elasticity and flexibility, reduced transmittance and improved conductivity.    DETAILED DESCRIPTION - The conductive film comprises a network of copper nanowires, a supportive material consisting of cellulose materials, glues, polymeric materials and overcoat materials, and a protective film over the copper nanowires. The conductive film has a sheet resistance of less than 10000 Omega /sq and a transparency of greater than 60%. The copper nanowires comprise a copper stick attached to a spherical copper nanoparticle. The copper stick has a first end and a second end, a length of 1-500 microns, and a diameter of 20-300 nm. The spherical copper nanoparticle has a diameter of 30-1000 nm attached to the first end or the second end of the stick. The protective film comprises an organic molecule to protect copper from corrosion, a coating or a thin layer of protective polymer. INDEPENDENT CLAIMS are included for:    (1) a dispersion of copper nanowires;    (2) a method of producing copper nanowires; and    (3) a method of making a conductive film.    DESCRIPTION OF DRAWING(S) - The diagram shows a scanning electron microscope image of copper nanowires growing out of nanoparticles at reaction times of 3.5-20 minutes respectively.
