Method for Attaching Silver Nanoparticles on Carbon Nanotubes一種簡單製備銀納米顆粒修飾的碳納米管的方法

总结

The present invention proposes a very simple approach for the decoration of carbon nanotubes (CNTs) with silver nanoparticles. CNTs are dispersed in ethylene glycol via ultrasonication, which is heated at 160oC and mixed with silver solution. The resulting silver-CNT nanohybrid comprises of carbon nanotubes as the template and silver nanoparticles with diameter less than 10 nm decorated onto the CNT surface. The process described in this invention has distinct advantages of simplicity, being easy to be scaled-up for mass production and uniform particle size over any similar techniques of attaching silver nanoparticles on CNT surface.

技术优势

1. A novel method for the fabrication of silver decorated carbon nanotubes (CNTs)
2. Uniform decoration of silver nanoparticles with diameter less than 10 nm on CNT surface
3. Useful to integrate the properties of the two components in hybrid materials
4. Much improved electrical/thermal conductivity of silver-decorated CNT
5. Very simple process with capabilities for mass production
6. Undamaged wall structure of CNT after silver decoration process
