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. 1. A preparation method for silver nanowires , comprising the following steps:(1) dissolving a dispersant in a tribasic alcohol to get a viscous clear solution;(2) dissolving silver nitrate in a tribasic alcohol to get a clear solution;(3) adding the silver nitrate/tribasic alcohol solution to the dispersant/tribasic alcohol solution for uniform mixing, finally, transferring the mixed solution into a reaction kettle, reacting at 170-200° C. for 7-8 hours, and cooling in cold water to obtain a mother solution containing silver nanowires; and(4) diluting the mother solution containing the silver nanowires with absolute alcohol, and centrifuging to obtain the silver nanowires.2. The preparation method for silver nanowires according to claim 1 , wherein the dispersant in step (1) is polyvinylpyrrolidone.3. The preparation method for silver nanowires according to claim 1 , wherein the tribasic alcohol is an analytically pure glycerol solution.4. The preparation method for silver nanowires according to claim 2 , wherein in step (3) claim 2 , 40 ml claim 2 , 0.05M silver nitrate/tribasic alcohol solution is added into 60 ml claim 2 , 0.67M polyvinylpyrrolidone/tribasic alcohol solution for uniform stirring and mixing.5. The preparation method for silver nanowires according to claim 3 , wherein in step (3) claim 3 , 40 ml claim 3 ...
