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.

Graphene is a unique two-dimensional (2D) structure of monolayer carbon atoms packed into a dense honeycomb crystal that has attracted great interest due to its diverse and fascinating properties.

Professor Gogotsi and Dr. Shuck introduce MXenes: a promising family of two-dimensional materials with a unique combination of high conductivity, hydrophilicity, and extensive tunability.

Graphene is a one-atomic-layer thick two-dimensional material made of carbon atoms arranged in a honeycomb structure. Its fascinating electrical, optical, and mechanical properties ignited enormous interdisciplinary interest from the physics, chemistry, and materials science fields.

Since its discovery little more than a decade ago,1 the two-dimensional (2D) allotrope of carbon—graphene—has been the subject of intense multidisciplinary research efforts.
