Gold nanoink 10-15 %wt
Characteristics of Gold nanoink
Mass fraction of gold: 10-15 weight%
Size of nanoparticles: <50 nm<
The composition of the dispersion of gold nano-ink:
- Gold nanoparticles (concentration 10-15 wt %)
- Oleylamine (as a stabilizer)
- Terpene alcohol (as a solvent)
* Gold nanoink may also contain trace amounts of sodium borohydride, sodium citrate, toluene,
ethanol, acetone.
According to the results of scanning electron microscopy, the gold nanoparticles have a spherical shape and narrow particle size distribution of 15 ± 4 nm.
