Laser-induced graphene (LIG), which is directly fabricated by laser carbonization of polymers, has gained much attention in recent years since its first discovery in 2014. This talk will focus on a unique bottom-up approach for directly growing different types of graphenic nanocarbons on polymer films by laser irradiation. The speaker will show how this direct-write process, often referred to as LIG, can be controlled to produce spatially-varying morphologies and chemical compositions of LIG, by leveraging gradients of laser fluence. Moreover, a method will be introduced to control the heteroatom doping of these LIG electrodes based on controlling the molecular structure of the polymer being lased. Finally, green applications of LIG such as antibacterial coatings, water treatment, innovative contaminant detection and electrocatalytic platforms will be presented.
