The article presents a study that investigates 'wetting transparency' for the metal substrates using theory and computer simulations. It is found that wetting transparency is a result of the van der Waals forces between the liquid and the substrate being able to 'see through' the graphene layer. It is also found that the wetting transparency of conformal graphene coatings may enable applications in which electronic and wetting properties can be independently controlled.
