Tunable Wettability of Graphene Nanostructures in Two-Phase Heat Transfer Applications

Due to the ever-increasing thermal challenges in advanced technologies, particularly in miniaturized electronics, I proposed the application of graphene-based coatings to tackle the device overheating issue. Knowing that the surface wetting state greatly affects the heat dissipation of any device, a simple and economical way is strategized to tune the surface wetting properties of graphene-based coatings. With a desirable wetting state applied onto the surface of the device, an extraordinary improvement in heat dissipation is achieved through water cooling. The findings in this study are anticipated to contribute greatly to the field of surface science, thermal engineering, and electronics heat management.
