Methods for production of silver nanostructures
Methods for producing silver nanostructures with improved dimensional control, yield, purity, monodispersity, and scale of synthesis.
1. A method of producing silver nanowires, the method comprising:
heating at least one polyol;
forming a mixture by adding a halide to the heated at least one polyol during the production of the silver nanowires;
adding at least one silver precursor to the mixture;
adding a polyvinyl pyrrolidone (PVP) solution to the mixture; and
isolating silver nanowires from the mixture.
2. The method of claim 1 , wherein the halide is a chloride.
3. The method of claim 2 , wherein the chloride comprises hydrochloric acid (HCl).
4. The method of claim 2 , wherein the chloride included in the mixture is in a concentration ranging from about 0.1 mM to about 0.4 mM.
5. The method of claim 1 , wherein the at least one polyol is heated to a temperature ranging from about 130° C. to about 150° C.
6. The method of claim 1 , wherein the at least one polyol is heated to a temperature up to about 140° C.
7. The method of claim 1 , wherein the mixture is maintained at a temperature ranging from about 130° C. to about 150° C.
8. The method of claim 1 , wherein the mixture is maintained at a temperature up to about 140° C.
