Enabling the Graphene Era
Laser-Induced Graphene or LIG is a 3D porous, conductive carbon coating that can be generated on many types of polymer or carbon surfaces.
LIG is an environmentally friendly, commercially viable, and scalable process since it uses no solvents or chemical reagents and only a common laser as found in any machine shop.
To produce laser-induced graphene, a 10.6 μm laser photothermally heats the carbon precursor to > 2500 ℃ over the span of microseconds.
This results in rapid outgassing of non-carbon elements and it promotes sp2 hybridization of the remaining carbon. This combination of outgassing and sp2 hybridization results in the formation of the porous microstructure of LIG.

The cost-effective synthesis and patterning of graphene nanomaterials is a challenge. our approach solves the dilemma.
LIGC creates a one-step, scalable approach for producing and patterning 3D networks of porous graphene films from commercial polymer films using a laser beam.
As the main hub for LIG technology, we offer an in-depth view of the LIG world and its scientific breakthroughs.
Our technology is based on the innovations made by Prof. James M. Tour, an internationally renowned chemist, and nanotechnologies from the Rice University with the association of Prof. Christopher J. Arnusch from the Ben Gurion University.
