example 1
[0021]0.16 g silver nitrate was dissolved at room temperature in 20 ml of glycerol to get a solution A; 5 g polyvinylpyrrolidone was dissolved at room temperature in 80 ml of glycerol to get a solution B; the solution A and the solution B were mixed uniformly to form a solution C; then, 5 ml of ultrapure water was added into the solution C and mixed uniformly to form a solution D, finally, the solution D was transferred into a reaction kettle, the reaction kettle was put into an oven with a set temperature of 160° C., and the reaction ended after a certain time of reaction.
[0022]The Ag nanowire mother solution in the reaction kettle was diluted with alcohol and centrifuged twice to obtain precipitated silver nanowires having a diameter of 30-40 nm and a length of 10-20 μm, which were dispersed in isopropanol. FIG. 1 is a scanning electron microscope (SEM) diagram of a silver nanowire synthesized in Example 1.
