Inks for inkjet and screen printing
CamInk® is a graphene based electrically conductive ink that is compatible with a variety of printing processes including inkjet and screen printing. The printable ink can be used in a variety of applications including: sensors, touch screens, RFID antennas, printed heaters, PCBs (Printed Circuit Boards), solar panels and electroluminescent (EL) panels.
The use of graphene in CamInk® presents a number of advantages over existing metal based conductive inks. Advantages include: light weight, flexibility, durability and no recyclability issues of the substrate as the ink is 100% metal free. In addition, a low loading fraction of graphene is needed to provide conductivity (0.1-10 wt% for graphene as compared to 45-65 wt% for silver).
We offer three grades of ink for inkjet printing, as well as inks suitable for screen printing.
