Application

Graphene dispersion formulated for screen printing.

Curing Condition: 250-350 °C, 20-30 min

The printed films are generally too thick for photonic annealing, so the substrate will need to be compatible with the thermal curing conditions (typically 250-300 C for 30 minutes works well for most applications). Suggested substrates include Si/SiO2 and polyimide.

This product can be used in material extrusion 3D printing technique.
