<p>The present invention relates to a method for preparing a silver nanofiber, and more specifically, to a method for preparing a silver nanofiber, the method comprising the steps of preparing a spinning solution containing a silver precursor, a reductant, a viscosity adjuster, and a solvent, wherein the viscosity adjuster is selected from the group consisting of dextran, alginate, chitosan, guar gum, starch, carboxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, xanthan gum, carboxyvinyl polymer, pectin, sodium alginate, and a combination thereof; performing electrospinning using the spinning solution; and performing multiple stages of primary, secondary, and tertiary heat treatment at a temperature range of 50-300°C. According to the present invention, the viscosity adjuster is used to maintain the viscosity to be suitable for spinning of the silver nanofiber, thereby improving the quality of the silver nanofiber, and a silver nanofiber having a high degree of crystallization and a high aspect ratio can be prepared.</p> |
