One-step and Cost-effective Conversion of Polyimide to Graphene by Utilizing a Desktop Laser

Herein a one-step, cost-effective, chemical-free, and versatile graphene fabrication by employing a CO2 laser is presented. A cost-effective desktop laser, compared to expensive and bulky lasers reported in the literature, is utilized for the conversion of polyimide films to graphene. Optimization of the fabrication is enabled by the examination of laser parameters such as laser power and scanning speed. Also, various 2D pattern drawings and in-situ fabrication were realized by the Laser Draw software. Furthermore, characterization experiments such as Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Raman Spectroscopy, and X-Ray Photon Spectroscopy (XPS) were performed to prove the successive graphene fabrication.
