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.

Abstract

The invention is the inorganic metal nanometer material technology domain, specifically involves through the liquid phase reaction to synthesize silver nanometer method. Mainly includes taking quaternary ammonium-the positive ion Gemini surface active agent as the template medicinal preparation, take six methylene butylamine as the reducing agent, prepared the high major axis ratio through the hydrothermal synthesis method, the sliver nanometer role with homogeneous diameter. Advantages: cost is low, good crystallizing, production rate is higher.

Description

technical field [0001] The invention belongs to the technical field of inorganic nanometer materials, and in particular relates to a preparation method of silver nanowires with high aspect ratio and uniform diameter. Background technique [0002] In recent years, one-dimensional nanostructures (nanowires, rods, ribbons, tubes) have been extensively studied due to their exotic applications in mesoscopic physics and fabrication of nanodevices. It is generally accepted that one-dimensional nanostructures exhibit electronic, thermal conductivity, and mechanical properties due to dimensional and quantum size effects. At the same time, it is considered as a linker and functional unit for the preparation of electronic, optoelectronic, electrochemical and electromechanical nanodevices. Compared with quantum dots and quantum wells, until recently, the progress of one-dimensional structures was relatively slow, mainly due to the difficulty in controlling the size, morphology, and pur...
