Title:
PROCESS FOR PRODUCING SILVER NANOWIRES
Document Type and Number:
WIPO Patent Application WO/2012/022332
Kind Code:
A3
Abstract:
The present invention provides a process for producing silver nanowires. The process comprises the steps of: a) providing a reaction mixture comprising a polyol, an organic chemical which is adsorbed on a silver surface, a chemical which forms a halide and/or one which forms a pseudohalide, the halide-forming chemical being a salt of one of the halides Cl-, Br- and/or I-, and the pseudohalide-forming chemical being a salt of one of the pseudohalides SCN-, CN-, OCN- and/or CNO-, a chemical which forms a redox pair and is selected from the group consisting of bromine, iodine, vanadium and mixtures thereof, b) adding a silver salt in an amount such that the concentration of silver in the reaction mixture is at least 0.5% by weight, based on the total weight of the reaction mixture, the silver salt being added at a temperature of the reaction mixture of at least 100°C, c) maintaining the temperature of the reaction mixture of 100°C for the duration of the reaction.
