Embodiment 1
[0067] According to the following method, silver nanowires with high aspect ratio, high purity and ultra-thin end-capping layer are prepared and applied to the preparation of transparent conductive films.
[0068] 1) Melamine was heat-treated at room temperature 550°C for 4 hours, and the heating rate was 2°C / min to obtain block C 3 N 4 powder; block C 3 N 4 Put 0.005g of the powder in 100mL of deionized water, and ultrasonically obtain ultrathin nanosheets (g-C 3 N 4 ), centrifuged at 10000rpm to obtain g-C containing stripped 3 N 4 supernatant;
[0069] 2) the g-C prepared above 3 N 4 The nanosheet solution was mixed with NVP (volume ratio 1:4) and stirred, and then irradiated vertically under a 360nm 12W UV lamp for 4h to form a fully transparent high-viscosity hydrogel.
[0070] 3) Add 1.0g CN / NVP hydrogel (the molar ratio of NVP to total Ag is 10:1) and 20mL EG solution in a 250mL round-bottomed flask, stir in an oil bath and raise the temperature to 160°C and K...
Embodiment 2
[0075] 1) In a 250mL round bottom flask, add 0.7g CN / NVP hydrogel (same as Example 1; the molar ratio of converted NVP to total Ag is 7:1) and 20mL EG solution, stir magnetically in an oil bath and Raise the temperature to 160°C and maintain a constant temperature for 1h. Subsequently, 35 μL of 0.01mol / L CuCl was added to the mixed solution 2 / EG solution, keep the constant temperature for 30min, then add 70μL 0.01mol / LAgNO 3 / EG solution was added to the above mixed solution and kept at a constant temperature for 35 minutes to promote the formation of five-twinned Ag nano-seeds;
[0076] 2) Inject 7 mL of 0.1 mol / LAgNO into the round bottom flask at a rate of 0.5 mL / min through a dual-channel syringe pump 3 / EG solution. The reaction was continued at 160° C. for about 30 minutes, and then the silver nanowire mixture was naturally cooled to room temperature. The obtained CN / NVP-coated silver nanowires were collected by centrifugation at 2000 rpm for 10 min, and then disper...
