Understanding the role of temperature in modulating surface adhesion properties of graphene and its derivatives is essential for their effective integration in nano- and optoelectronic devices. In this study, the temperature-dependent dispersive and polar components of work of adhesion was systematically investigated across graphene (G), reduced graphene oxide (rGO), and graphene oxide (GO), using inverse gas chromatography (IGC) and selected polar/nonpolar solvent interactions. Our results reveal a consistent hierarchy in adhesion energies (G > rGO > GO) and show that elevated temperatures significantly influence interfacial interactions by modifying surface energy components. Furthermore, the solvent-specific trends suggest a strong interplay between molecular polarity and surface functionalization. This study not only provides thermodynamic insights into graphene-based adhesion but also contributes to rational interface engineering in 2D materials under thermal fluctuation.

Surface Tension, Capillary Action, and Viscosity
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...
