Silver nanoparticles ink for inkjet printing

Smart′Ink C47NJET10020 conductive ink was developed for the printed electronics, is particularly well suited for applications requiring high conductivity and high resolution. This ink, based on silver, is perfectly adapted to design conductive traces on flexible substrates. This non-toxic nano silver ink is suited to design high resolution conductive patterns on flexible substrates for applications such as antennas, sensors, OPV and OLED grids, electrodes and touchscreen bezel busbars.


Smart′Ink C47NJET10020 conductive ink shows improved jetting performance and is successfully used on different tools such as Drop on Demand (DOD) inkjet printer FUJIFILM Dimatix, or such as digital micro-dispensing inkjet printer Microdrop and Microfab.

Product benefits:

• Very high electrical conductivity.
• Low curing temperature for printing on flexible substrates.
• Non CMR ink.
• Compatible with various curing process including photonic, IR, low vacuum oven and thermal.
• Unchanged conductivity on bending.
• Good adhesion (5B-ASTM D3359) on various flexible substrates (PET, PEN and Kapton).Recommended surface treatment: temperature stabilization, argon plasma.

Typical processing guideline

• Smart′Ink C47NJET10020 conductive ink is warmed to room temperature (about 10 minutes) and left for 5 minutes in an ultrasonic bath in order to get rid of any aggregates.
• Filtration on a 0.45 μm PTFE filter syringe to avoid any nozzles clogging.

• Qualified printheads: RICOH (MH5420), XAAR (1003 GS6, 128), KONIKA MINOLTA (KM512SHx, KM1024iMHE, KM1024LHB), FUJIFILM (Dimatrix DMP series cartridge)
• Storage stability: 6 months (fridge)
• Sintering conditions:

Tunnel furnace: 120°C/5min for 20mW.cm; 150°C/5min for 6mW.cm; 180°C/5min for 3.8mW.cm; 200°C/5min for 2.8mW.cm.
NIR: few seconds for 4-10mW.cm.
Photonic curing: <100 ms for 3-10mW.cm.
