How universal is the wetting aging in 2D materials

Previous studies indicate that 2D materials such as graphene, WS2 and MoS2 deposited on oxidized silicon substrate are susceptible to aging due to the adsorption of airborne contamination. As a result, their surfaces become more hydrophobic. However, it is not clear how ubiquitous such a hydrophobisation is, and the interplay between the specific adsorbed species and resultant wetting aging ...
