Biomass‐Derived Laser‐Induced Graphene: From Precursor Chemistry to Device Integration
ABSTRACT Laser direct writing provides a mask‐free route for converting suitable carbon‐containing precursors into patterned, porous, and conductive laser‐induced graphene (LIG) networks. Although LIG was initially demonstrated mainly using aromatic synthetic polymers, such as polyimide, biomass precursors introduce renewable feedstocks with highly ...
