Abstract
Laser-induced graphene (LIG) is a newly emerging 3D porous carbon materials, fabricated via direct laser scribing of carbon precursors. LIG exhibits excellent electrical conductivity and good mechanical performance, with tunable microstructure and surface properties. This review provides a comprehensive summary of the recent advancements in surface-functionalized LIG for flexible sensors. The methods for surface and interface functionalization of LIG are firstly introduced, followed by an emphasis on the potential of surface functionalized LIG for advanced applications in physical sensors, electrochemical sensors, and biosensors. Finally, the current challenges and future perspectives of surface functionalized LIG research are discussed.
