摘要
The present invention relates to a method for producing gold nanowires through a solution process, and one embodiment of the present invention relates to a method for producing a gold nanowire comprising a first step of producing a mixed solution containing poly (diallyldimethyl ammonium chloride), a polyol and a gold precursor, A second step of forming a gold having an oxidation state of +1 by a first reduction of the gold precursor by heat treatment, a second step of reducing a gold having an oxidation state of +1 by mixing a nucleating agent with a solution having completed the second step, A fourth step of growing the gold nanocrystals into gold nanowires, and a fifth step of purifying the solution of the fourth step to obtain gold nanowires, wherein the poly (diallyldimethyl ammonium chloride) Is used as a reaction rate controlling agent to control the reaction rate, gold nanocrystals can be grown in one direction to form gold nanowires having an aspect ratio of 5000 or more, and the plastic deformation of gold nanowires And a gold nanowire having a diameter of 75 nm or more and thick can be produced with a high yield.
