Multi-Walled Carbon Nanotube (MWCNT) Aqueous Ink, Conductive Ink

Single-Walled Carbon Nanotube (SWCNT) Aqueous Ink, Conductive Ink

Performance Parameters

Catalog Number	NM-CINK001
Quantity	1 ltr (1,000 ml)
Viscosity (low viscosity ink formulation for drop on demand- DOD inkjet, ultrasonic aerosol jet printing, air-brush, blade, slot die coating technologies)	40.0-50.0 mPa·s [cP] (measured at @ 25 Deg C, shear rate 1000 s^-1)
Conductive Phase	Multi-walled carbon nanotubes (MWCNTs) of 9-10 nm in diameter and aver. 1.5 μm of lengths; highly crystalline and quality of MWCNTs
Solid Content of Multi-Walled Carbon Nanotubes (MWCNTs)	0.8-1.0 and up to 2.5 wt.% (8.0-10.0 mg/ml and up to 25.0 mg/ml) **@ 2.5 wt.% (25.0 mg/ml) viscosity is 80.0-100.0 mPa·s [cP] (i) the CNT solid content could vary depending on the final application and on the printing technique to be applied; (ii) Polyvinylpyrrolidone: PVP can be added as additive/viscosity modifier and dispersant, to result into 100-1,000 cP or even above 3,000-4,000 cP e.g., for screen printing and or flexography printing applications
Solvent Medium	Distilled water (d-H₂O) surfactant medium (pH: slightly acidic 6.0-6.5) with/without PVP as viscosity modifier (if needed)
Drying-Annealing-Sintering Temperature/Conductivity	10 min @80 °C and 10 min @110 °C, or 20 min @110 °C to achieve: <50.0 Ohm@1cm interelectrode distance (measured using a multimeter) Electrical conductivity (σ): 3-4 x 10³ S/m
Storage	Storage at room temperature (23-25 °C) in ambient conditions (if available storage in a fridge at 2-8 °C) The ink must be warmed at room temperature before use
Details of Usage	Keep in opaque plastic container or in aluminium foil covered glass vials Needs to be agitated before use (e.g. 20 sec mildly), 10 min of magnetic stirring@1,000 rpm and 5 min of bath sonication before use. Clean with its solvent medium: H₂O or a mixture of H₂O: Ethanol: Isopropanol (1:1:1) for e.g. cartridges, aerosol-jet nozzles, beakers, etc. Clean metallic parts e.g. of the printer (nozzles, printer head, etc.) with H₂O or a mixture of H₂O: Ethanol: Isopropanol (1:1:1) in an ultrasonic bath for at least 30 min. Soluble in H₂O (can be diluted up to two times from the original suspension) Low electrical resistivity ink, good adhesion to a wide range of hydrophilic or polar substrates since the dispersion is in H₂O. Always wear a mask in the printing-cleaning process
