Synthesis of Laser-Induced Graphene via Laser Irradiation

Laser-Induced Graphene (LIG) is a graphitic material with properties comparable to more pure forms of graphene, but with a simpler and cheaper synthesis process. By irradiating a carbon-rich precursor with a laser, LIG samples can be formed in a matter of seconds instead of hours. In this work, we aim to show that the synthesis of LIG using consumer-grade equipment is an effective method. The graphene content of the LIG was confirmed by Raman analysis, and Hall measurements showed a low sheet resistance. Our findings indicate that LIG could be better suited to certain applications, such as biomedical research, than other methods of graphene synthesis.
