Thaddeus Golbek and Tobias Weidner have a joint paper with researchers from China and Germany in Nano Letters about ageing of 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 ...
