As per the supplier, for spin-coating on glass, a standard iterative solvent cleaning protocol is recommended, involving 5 minutes of sonic cleaning in acetone, ethanol, and isopropanol, followed by blow-drying with N2 between each step, and then ozone plasma treatment (medium power for 2-5 minutes) to promote adhesion. The ink is also compatible with spin-coating on Si/SiO2 substrates, which can undergo the same pre-treatment protocol. When using the spin coater, spinning a single layer at 2000-5000 rpm results in a final film thickness of 40-60 nm. To achieve thicker films, multiple layers can be applied without a baking step, which is recommended over using a lower spin speed to maintain film uniformity. With 5 coats at 2000 rpm, a 200 nm thick film is obtained after baking at 300 °C for 30 minutes in air.

Description générale
Application
Spin-coating a single layer at 2000-5000 rpm yields a final film thickness of 40-60 nm. To achieve thicker films, multiple layers can be applied without a baking step. This is recommended over using a lower spin speed to maintain film uniformity. This ink should work on almost any substrate.
Electrical performance:
Following a baking step at 300 °C for 30 minutes in air, the spin-coated films exhibit sheet resistance of 300-800 Ω/sq, corresponding to a resistivity of 0.003-0.004 Ω−cm. With 5 coats at 2000 rpm, a 200 nm thick film with a sheet resistance of 160 Ω/sq. is obtained.
General guidelines:
Ethanol is recommended for cleaning up the ink and dried films, as well as dilution. Bath sonication (5-10 minutes) of the ink prior to use is recommended following extended periods of disuse.
