Abstract
A preparation method for silver nanowires, including: dissolving a dispersant in a tribasic alcohol to get a viscous clear solution, dissolving the silver nitrate in a tribasic alcohol to get a clear solution; then, adding the silver nitrate solution to the dispersant solution for uniform mixing, finally, transferring the mixed solution into a reaction kettle, putting into an oven with a set temperature (170˜200° C.), and ending the reaction after a period of time. The mother solution of silver nanowires is diluted with alcohol and then centrifuged to separate organics, the novel silver nanowires with a uniform aspect ratio and nodes are obtained.
