Embodiment 1
[0066] Add 250-4500ml of deionized water to a 500-5000ml beaker, and add 2-36ml of bacterial cellulose dispersion with a concentration of 1mg / ml, and continuously perform magnetic stirring (rotation speed 200 rpm) during the reaction; add 50-900mg Polyvinylpyrrolidone (PVP), add 0.1-1.8g copper chloride dihydrate (CuCl 2 ·2H 2 0), add 5-90ml of hydrazine hydrate solution after 20min again, after 30min of reaction, pour the solution containing copper nanowires into 600 mesh stainless steel filter mesh sieve, filter and repeatedly wash with ethanol several times, then re-disperse it in a small amount of ethanol, placed in the lining of a 500ml polytetrafluoroethylene reaction kettle, oven-dried at 60°C, and then placed in a tube furnace for annealing at 200-400°C for 2-8h (5°C / min liter) under a hydrogen-argon atmosphere. cooling rate), copper nanowires can be obtained.

Embodiment 2
[0070] The overall implementation steps of this example are the same as those of Example 1, and the difference from Example 1 is that the entire reaction process is in an ice bath environment. In the ice bath environment, the reaction rate was slower and the surface state of the resulting copper nanowires was more uniform.
[0071] Figure 3A , 3B A scanning electron microscope photograph of copper nanowires prepared in a method for preparing biomass-derived copper nanowires provided in Example 2 of the present disclosure is schematically shown.
[0072] like Figure 3A , 3B As shown, the morphology of the copper nanowires obtained in this example is more uniform and plump than the copper nanowires obtained in Example 1.
Embodiment 3
[0074] The overall implementation steps of this example are the same as those of Example 1, and the difference from Example 1 is that the surfactant is sodium dodecyl sulfonate.
[0075] Figure 4A , 4B A scanning electron microscope photograph of copper nanowires prepared in a method for preparing biomass-derived copper nanowires provided in Example 3 of the present disclosure is schematically shown.
[0076] like Figure 4A , 4B As shown, the copper nanowires obtained in this example have good morphological characteristics.
