Examples
Embodiment 1
[0050] Weigh 40.77g of silver nitrate and 39.96g of polyvinylpyrrolidone K30, add them into 300ml of ethylene glycol, and dissolve them in a 500W ultrasonic water bath to obtain a uniform mixed solution.
[0051] Weigh 1.38g CuCl respectively 2 and 2g of stress-free steel fiber (301) were added to the above mixed solution, and the reaction mother solution was obtained by ultrasonication.
[0052] The reaction mother liquor was transferred to a 500ml three-neck flask, and the reaction was carried out at 170° C. for 120 minutes to obtain a mixture. The mixture was centrifuged and the precipitate was collected to obtain the silver nanowires.
[0053] figure 1 It is the scanning electron micrograph of the silver nanowire prepared in embodiment 1, by figure 1 It can be seen that silver nanowires without particles have been prepared, and the purity of the silver nanowires is high (the number of silver wires is >99%).
Embodiment 2
[0055] Weigh 5.09g of silver nitrate and 4.99g of polyvinylpyrrolidone K30, add them into 300ml of ethylene glycol, and dissolve them in a 500W ultrasonic water bath to obtain a uniform mixed solution.
[0056] Weigh 0.17g CuCl respectively 2 and 0.6 g of stress-free steel fibers were added to the above mixed solution, and the reaction mother solution was obtained by ultrasonication.
[0057] The reaction mother liquor was transferred to a 500ml three-necked flask, and the reaction was carried out at 170° C. for 60 minutes to obtain a mixture. The mixture was centrifuged and the precipitate was collected to obtain the silver nanowires.
[0058] figure 2 It is the scanning electron micrograph of the silver nanowire prepared in embodiment 2, by figure 2 It can be seen that silver nanowires without particles have been prepared, and the purity of the silver nanowires is high (the number of silver wires is >99%).
Embodiment 3
[0060] Weigh 91.73g of silver nitrate and 89.91g of polyvinylpyrrolidone K30, add them into 300ml of ethylene glycol, and dissolve them in a 500W ultrasonic water bath to obtain a uniform mixed solution.
[0061] Weigh 3.11g CuCl respectively 2 and 4.5g of unstressed steel fiber (304) were added to the above mixed solution, and the reaction mother solution was obtained by ultrasonication.
[0062] The reaction mother liquor was transferred to a 500ml three-neck flask, and the reaction was carried out at 170° C. for 300 minutes to obtain a mixture. The mixture was centrifuged and the precipitate was collected to obtain the silver nanowires.
[0063] image 3 It is the scanning electron micrograph of the silver nanowire prepared in embodiment 3, by image 3 It can be seen that silver nanowires without particles have been prepared, and the purity of the silver nanowires is high (the number of silver wires is >99%).
