Composite structure of graphene sheet coated with nano film will be newly developed type structural materials. Hence, the mechanical properties of interface layer between graphene sheet and coating materials is crucial to fabricate the graphene nanoribbons (GNRs) when subjected to thermal loading. In present study, the thermal stress of GNRs with coating nano film is investigated using a proposed model. In the analytical approach, the interface between GNRs and coating materials is considered as a bounding connection by van der Waals (vdW) forces. The normal stress and the shear stress in the interface are obtained by the explicit closed form solution of governing equation for GNRs coated by nano film. The result shows that the maximum shear stress occurs always at the free edge, and much larger than the normal stress. The shear stress in the interface does not change sign, but the normal stress can change from the compression to the tensile, or inverse variation.
