Laser-Induced Graphene Composites as Multifunctional Surfaces

Laser-induced graphene (LIG) is a platform material for numerous applications. Despite its ease in synthesis, LIG's potential for use in some applications is limited by its robustness on substrates. Here, using a simple infiltration method, we develop LIG composites (LIGCs) with physical properties that are engineered on various substrate materials. The physical properties include surface properties such as superhydrophobicity and antibiofouling; the LIGCs are useful in antibacterial applications and Joule-heating applications and as resistive memory device substrates.
