CONDUCTIVE GRAPHENE INK

Nanotech developed proprietary chemical processes for the large scale production of graphene (technically it is reduced graphene oxide) with largest surface area (1600 m2/g) and electrical conductivity (7700 S/m) combined. We use this unparalleled graphene for making high quality and environmentally friendly conductive inks. These inks utilize proprietary dispersants and binders to produce graphene coatings with excellent mechanical properties, making them ideal for flexible and printed electronics. We can work with you to custom make graphene inks specifically designed for your application.

ELECTRICAL PROPERTIES OF COATED FILMS

DATA MEASUREMENT NOTES
Sheet Resistence Nominal: less than 40 ohm/sq/mil Typical: 32 ohm/sq/mil Nanotech is currently developing graphene ink with a sheet resistance of less than 10 ohm/sq/mil. Stay tuned!
Mechanical properties Compression (concave) bending. By creasing at 180 degrees (2 mm bend radius) and straightening the film back to the original flat state, only -0.1 % change in resistance was observed.
Mechanical properties Tension (Convex) bending. Crease at 180 degrees (1.75 mm bend radius) causes +0.74 % increase in resistance.
Stability -1.3 % change in resistance after 1000 bending cycles. Measured by bending the films (compression) back and forth at 10 mm radius for 1000 cycles.
Curing Conditions Temperature of 80 degree Celsius. Takes 3-5 minutes.

SHEET RESISTENCE

Our graphene ink can be coated onto
films showing very stable sheet resistance against bending and twisting. When the electrodes are bent back and forth for 1000 times, only 1.3% change was observed.

CONDUCTIVE GRAPHENE INKS

Why we are the finest conductive ink on the market. Nanotech Energy starts with the finest Reduced Graphene Oxide there is. Tested against others we have on average 100 times more surface area than any RGO and Graphene we have tested. Our conductive ink is environmentally friendly, we are carbon based and spills will not hurt the environment. Other conductive Inks on the market are made with materials such as silver and other expensive materials. Our conductive Ink parameters can be adjusted depending on the application: concentration of graphene, particle size, surface tension, viscosity and etc.
