[0034] Example 1
[0035] A method for preparing high-yield nano silver wires includes the following steps:
[0036] 1) Add 0.8g of PVP with a molecular weight of 40,000 and 0.8g of PVP with a molecular weight of 400,000 to the reaction vessel, then add 200mL of ethylene glycol solution, and place the reaction vessel containing the above solution in a thermostatic magnetic stirrer for stirring. The temperature is 140°C, the stirring speed is 150rpm, and the stirring time is 120min;
[0037] 2) Add 18 mL of ferric chloride ethylene glycol solution (0.0005g / mL) that has been stirred at room temperature for more than 120 minutes into the reaction vessel, and continue stirring for 30 minutes at a temperature of 140°C at a speed of 150 rpm;
[0038] 3) Subsequently, 24 mL of silver nitrate glycol solution (0.05g / mL) that has been stirred at room temperature for more than 30 minutes was added dropwise to the reaction vessel with a dropping rate of 0.5mL / min. After all the drops were comp
