Nink-1000 multiwall carbon nanotube ink

1.5 inch squares of Nink were printed using an HP Deskjet 960C onto overhead transparency film and also onto standard copier paper (20 lb). The following sheet resistance data is an average of 5 pages, measured after each printing and a 2 minute drying step at 80C. Test setup We loosely followed ASTM D-254 in the measurement of the sheet resistance. We prepared a 1" square test fixture, consisting of two brass contacts, separated by a 1" square insulator, as shown below. The fixture was firmly held against the printed sheet, and resistance was measured using a Keithley Sourcemeter 2400.

The NanoLab "Nink" products are carbon nanotube inks for direct printing of nanotube electronics and sensors. This ink contains carboxyl (COOH) functionalized carbon nanotubes in an aqueous suspension with the minimum concentration of additives to impart long term stability and printability to the ink. NanoLab produces two types of ink, Nink-1000 (multiwall carbon nanotube ink) and Nink-1100 (single wall carbon nanotube ink).NanoLab formulated Nink to be printable using Fuji's Dimatix TM series printers.
