UTDAg Conductive Silver Nanoinks 
                             

UTDAg silver nanoink is general-use ink for aerosol or ink-jet printing on variety of substrates. UTDAg is based on silver nanoparticles with average size around 10 nm and dispersed in liquid vehicle. Since it is surface stabilized, UTDAg inks are highly soluble in nonpolar organic solvent and stable under atmospheric conditions at room temperature. 

 

Key Ink Properties

Particle Size           

~ 7 - 10 nm

Silver concentration    

~ 10-50%

Solvent 

Hydrocarbon

Viscosity, can be controlled

1 - 10 cP

Shelf life

>3 months at room temperature

 







Silver nanoparticles have low sintering temperature and can be used on inexpensive substrates, such as paper, polyester, polyimide and others. The resistivity of UTDAg ink decreases with time at required temperature.

UTDAu Conductive Gold Nanoinks
                          


UTDAu gold nanoink is general-use ink for aerosol or ink-jet printing on variety of substrates. UTDAu is based on gold nanoparticles with average size around 4 nm and dispersed in liquid vehicle. Since it is surface stabilized, UTDAu inks are highly soluble in nonpolar organic solvent and stable under atmospheric conditions at room temperature. 

 

Key Ink Properties

Particle Size           

~ 3 - 5 nm

Gold concentration    

~ 25 – 40 wt%

Solvent 

Hydrocarbon

Viscosity,  can be adjusted for specific application by addition of cosolvent

1 - 10 cP

Shelf life

6 months at room temperature
