Graphene partially screens van der Waals interactions depending on layer thickness, study reveals  

Two-dimensional (2D) materials, which are only a few atoms thick, are known to exhibit unique electrical, mechanical and optical properties, which differ considerably from the properties of bulk materials. Some recent studies have also been probing these materials’ “transparency” to intermolecular interactions, such as van der Waals (vdW) forces—weak forces arising from fluctuating electrical charges, which prompt the attraction between molecules or surfaces.
