UNIFORM ASPECT RATIO SILVER NANOWIRES PREPARATION METHOD

A preparation method for silver nanowires with a uniform aspect ratio, including: dissolving at a certain temperature silver nitrate in glycerol to get a solution A; dissolving at a certain temperature polyvinylpyrrolidone (PVP) in glycerol to get a solution B; mixing uniformly the solution A and the solution B to form a solution C; then, adding a certain amount of a medium into the solution C and mixing uniformly to form a solution D, finally, transferring the solution D into a reaction kettle, putting the reaction kettle into an oven with a set temperature, and ending the reaction after a certain time of reaction. The reactants are centrifuged twice to obtain precipitated silver nanowires. With the addition of the medium, the method can improve the moving speed of ions in a reaction solution, and obtain the silver nanowires with a uniform aspect ratio and nodes. The preparation method is simple and easy to operate, experimentally stable, and suitable for industrial production.
