General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product belongs to Enabling category of greener alternatives thus aligns with "Design for energy efficency". Graphene inks are highly conductive, low cost and super flexible. Click here for more information.

Application

Spin-coating:
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.
