First claim
Opening claim text (preview).
1 - 22 . (canceled) 23 . A method of producing silver nanowires, the method comprising: providing a heated mixture including at least one halide, at least one silver precursor, and at least one capping agent in at least one polyol solvent; allowing the mixture to react whereby the at least one silver precursor is reduced to silver nanowires; and isolating the silver nanowires from the mixture. 24 . The method of claim 23 , wherein the at least one halide is a chloride. 25 . The method of claim 24 , wherein the chloride comprises hydrochloric acid or sodium chloride. 26 . The method of claim 24 , wherein the mixture comprises chloride at a concentration ranging from about 0.1 mM to about 0.4 mM. 27 . The method of claim 23 , wherein the heated mixture is at a temperature of up to about 150° C. 28 . The method of claim 23 , wherein the heated mixture is maintained at a temperature of up to about 150° C. 29 . The method of claim 23 , wherein the mixture comprises the at least one silver precursor at a concentration ranging from about 20 mM to about 30 mM. 30 . The method of claim 29 , wherein the at least one silver precursor is silver nitrate. 31 . The method of claim 23 , wherein the at least one capping agent is polyvinyl pyrrolidone (PVP) and the mixture comprises PVP at a concentration ranging from about 30 mM to about 40 mM. 32 . A method of producing silver nanowires, the method comprising: forming a heated mixture comprising halide ions, silver ions, at least one capping agent, and at least one polyol; forming silver nanowires by reducing the silver ions; and isolating the silver nanowires from the mixture. 33 . The method of claim 32 , wherein the halide ions are chloride ions and the mixture comprises chloride ions at a concentration ranging from about 0.1 mM to about 0.4 mM. 34 . The method of claim 32 , wherein the heated mixture is at a temperature of up to about 150° C. 35 . The method of claim 32 , wherein the heated mixture is maintained at a temperature of up to about 150° C. 36 . The method of claim 32 , wherein the mixture comprises silver ions at a concentration ranging from about 20 mM to about 30 mM. 37 . The method of claim 36 , wherein the silver ions are derived from silver nitrate. 38 . The method of claim 32 , wherein the at least one capping agent is polyvinyl pyrrolidone (PVP) and the mixture comprises PVP at a concentration ranging from about 30 mM to about 40 mM. 39 . A method of producing silver nanowires, the method comprising: providing a mixture including at least one halide, at least one silver precursor, and at least one capping agent in at least one polyol solvent; heating the mixture; allowing the mixture to react whereby the at least one silver precursor is reduced to silver nanowires; and isolating the silver nanowires from the mixture. 40 . The method of claim 39 , wherein the mixture comprises the at least one halide at a concentration ranging from about 0.1 mM to about 0.4 mM. 41 . The method of claim 39 , wherein the mixture comprises the at least one silver precursor at a concentration ranging from about 20 mM to about 30 mM. 42 . The method of claim 39 , wherein the mixture comprises the at least one capping agent at a concentration ranging from about 30 mM to about 40 mM.
