The influence of temperature on the graphene wettability in the range from 2 degrees C to 97 degrees C was investigated. The experimental and theoretical studies have shown that the water temperature, the roughness of the wall and the crystal orientation of the copper substrate significantly affect the wettability of graphene, as well as the structuring of water molecules and hydrogen bonds in the vicinity of the graphene surface. The lowest contact angle is obtained on graphene coating on copper with orientation (111). The lowest wettability of graphene corresponds to a copper substrate with orientation (110). Temperature noticeably distorts the structuring of water molecules near the graphene layer. Defects on the surface of the substrate in the form of a "spike" lead to the formation of graphene wrinkles, which result in local exfoliation of copper and graphene and in a change in the wettability of the graphene layer.
