Abstract:
1. A method for the production of silver nanowires comprising reacting: i) at least one polyol; ii) at least one silver compound capable of producing silver metal when reduced; and iii) at least one organic protective agent (OPA); as reactants in a reaction at a reaction temperature and under conditions that produce a product solution comprising at least 10 weight percent (10 wgt %) silver nanowires as compared with a weight percent of all other silver nanostructures in the product solution; a) wherein a ratio of total moles of silver (either as an ion or as metal) to a total volume of polyol or polyols (in liters) in the product solution is greater than or equal to 0.1 molar; and b) wherein a ratio of a molar concentration of the organic protective agent to a molar concentration of the silver (either as an ion or as metal) in the product solution is less than or equal to 10:1.
