Patent ID: 8465691

Claim:
A method for manufacturing indium tin oxide nanowires with a resistivity of about 10 −3 Ω-cm, the method comprising: preparing a precursor aqueous solution comprising a tin-containing specie and an indium-containing specie wherein the molar ratio of the tin-containing specie to the indium-containing specie is about 5 to about 15%; preparing a polymer solution comprising an organic solvent; mixing the precursor solution with the polymer solution to produce an electrospinning solution or sol-gel wherein together the tin-containing specie and the indium-containing specie are from about 2% to about 15% by weight of the electrospinning solution or sol-gel; electrospinning the electrospinning solution or sol-gel at a relative humidity from about 15 to about 60 percent while irradiating the electrospinning solution or sol-gel with infrared radiation to provide the indium-tin nanowires with a cross-sectional thickness of from about 1 to about 100 micrometers; drying the indium tin oxide nanowires at a drying temperature of about 100° C. to about 200° C. to a moisture content of less than about 20% by weight; heating the indium tin oxide nanowires, at a rate between about 2 and about 20° C. per minute from the drying temperature to a calcination temperature of from about 700° C. to about 1000° C.; and maintaining the calcination temperature for a time from two hours to one week to provide indium tin oxide nanowires with a resistivity of about 10 −3 Ω-cm.
