The invention relates to a method for preparing silver nanowires simply and quickly. The method comprises the steps of: adding a halogenated salt solution to a surfactant solution, adding silver nitrate, reacting in an oil bath at 120-200 ° C for 10-30 minutes, and finally Centrifuging, washing and separating silver nanowires; wherein the concentration of the surfactant solution is 4-90 g/L, the concentration of chloride ions in the halogenated salt is 0.195-0.705 mmol/L, and the concentration of bromide ions is 0.15-0.48 Mmmol/L. The invention adopts the chemical reduction method to prepare silver nanowires, and synthesizes silver nanowires with large long diameter, high purity and good dispersibility at a low cost in a short time, and the reagents used are green and environmentally friendly, and are simply added in one time. Each reactant eliminates the complexity of feeding by drop or stepwise; at the same time, the large reduction of reaction time can effectively improve production efficiency and reduce production cost. |
