Laser-induced graphene (LIG) is a graphitic material synthesized by laser writing a pattern on a carbon precursor. Different wavelengths of lasers have been used in this direct-writing process; in this work, we utilize a 450 nm wavelength bench top laser to create graphene using a polyimide precursor. By varying the intensity and focus of the incident beam, we have been able to create multilayer graphene, confirmed by Raman analysis. Scanning electron microscopy (SEM) and Hall measurements of the synthesized material has shown a highly porous structure with a large surface-area-to-volume ratio and low sheet resistance. The structure-property-processing-performance (SP3) correlations of LIG provide a good foundation for gas sensing studies.
