Example Embodiment
[0028] [Example 2] Under stirring, add hexamethylenetetramine to the silver nitrate solution at a molar ratio of 2:1 to silver nitrate, and mix Gemini surfactant 16-4-16 with silver nitrate. The molar ratio of 0.5 is dissolved in water. While stirring, slowly add the 16-4-16 solution dropwise to the silver nitrate and hexamethylenetetramine solution prepared above, and then transfer the resulting reaction solution to the autoclave, and react at 105°C. 18 hours. After cooling, the silver nanowires are separated and obtained. See Figures 2 and 3. From Figure 3 can It is known that the prepared silver nanowires have a face-centered cubic structure.
[0029] [Example 3] Under stirring, hexamethylenetetramine was added to the silver nitrate solution at a molar ratio of 4:1 to silver nitrate, and Gemini surfactant 16-6-16 was added to the silver nitrate solution. The molar ratio of 0.4 is dissolved in water. Under stirring, the Gemini surfactant 16-6-16 solution was slowly added dropwi...
Example Embodiment
[0031][Example 5] Under stirring, add hexamethylenetetramine to the silver nitrate solution at a molar ratio of 2:1 to silver nitrate, and mix Gemini surfactant 16-10-16 with silver nitrate. The molar ratio of 0.8 is dissolved in water. While stirring, slowly add the 16-10-16 solution dropwise to the silver nitrate and hexamethylenetetramine solution prepared above, and then transfer the resulting reaction solution to an autoclave and react at 150°C 8 hours. After cooling, the silver nanowires were separated and obtained. Such as Figure 6.
