A drastic reduction in silver concentration of metallic ink by the use of single-walled carbon nanotubes decorated with silver nanoparticles

The concentration of Ag nanoparticles in metallic inks was significantly decreased to 3 wt% by a small addition of single-walled carbon nanotubes decorated with Ag nanoparticles (0.003 wt%) while maintaining high conductivity. The stability was good, and conductive patterns were printed using an inkjet device.
