| Abstract |
Reduced graphene oxide (RGO) is a promising material with many applications, such as energy storage, drug delivery, environmental treatment, and sensors, owing to its numerous advantages. The techniques used to reduce oxygen functional groups to form RGO are high-temperature processes that are energy-intensive and environmentally unfriendly. In this work, we focused on improving RGO using laser-based methods to convert graphene oxide (GO) into RGO. This inexpensive process was performed efficiently under ambient conditions. RGO was reduced using direct laser writing (DLW) with a CO2 source, which involved a one-step ultrafast laser treatment with different laser powers, 6, 8, 10, and 12 W. This technique improves the removal of oxygen functional groups on graphene surfaces and decreases sheet resistance from 205 MΩ/sq to 0.22 MΩ/sq without affecting the graphene structure. This method achieves results within seconds and prevents reformation of oxygen chemical functional groups of under ambient air conditions. The results of this study may have significant implications for the development of advanced materials and the design of new laser-based processes for the production of RGO |
