摘要
Disclosed herein is a method for preparing ultrathin silver nanowires. It may comprise (a) dissolving a silver salt (Ag salt) and a capping agent in a reducing solvent to give a mixture solution; (b) adding a halide compound to the mixture solution to yield a silver seed; (c) heating the mixture solution and then allowing the heated mixture solution to grow ultrathin silver nanowires from the silver seed under a pressure in an inert gas atmosphere; and (d) cooling the mixture solution in which the ultrathin silver nanowires have grown, followed by purification and separation to obtain the ultrathin silver nanowires. The silver nanowires are restrained from growing in thickness under a certain pressure, so that they are 30 nm or less in thickness and have a narrow diameter distribution, which leads to an improvement in aspect ratio.
