Ultra-long silver nanowire material and fabrication method thereof

A fabrication method of a silver nanowire material, comprising the following steps:

• step 1:
• adding glucose and polyvinylpyrrolidone (PVP) to deionized water and thoroughly stirring to obtain a clear solution;
• wherein the glucose, the PVP, and the deionized water are in a molar ratio of 1:0.06:430, the molecular weight of the PVP is 1,300,000 daltons;
• step 2:
• adding an iron nitrate solution to the clear solution obtained in step 1 and thoroughly stirring to obtain a mixed solution A;
• wherein a molar ratio of iron nitrate to the glucose in the mixed solution A is 1:(480-600);
• step 3:
• adding a sodium chloride solution to the mixed solution A obtained in step 2 and thoroughly stirring to obtain a mixed solution B;
• wherein a molar ratio of sodium chloride to the iron nitrate in the mixed solution B is 1:(3-4.8);
• step 4:
• adding a silver nitrate solution dropwise to the mixed solution B obtained in step 3, stirring to obtain a reaction solution, transferring the reaction solution to a hydrothermal reactor, and conducting a reaction at 115° C. for 15 h to obtain a flocculent product;
• wherein a molar ratio of silver nitrate to the glucose in the reaction solution is 1:(300-500);
• and
• step 5:
• subjecting the flocculent product to sedimentation washing with deionized water and absolute ethanol successively to obtain the silver nanowire material.
