摘要：

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 hydrophobization is, and the interplay between the specific adsorbed species and resultant wetting aging remains elusive. Here, we report a pronounced and general hydrophilic-to-hydrophobic wetting aging on 2D InSe films, which is independent of the substrates to synthesize these films (silicon, glass, nickel, copper, aluminum oxide), though the extent of wetting aging is sensitive to the layer of films. Our findings are ascribed to the occurrence and enrichment of airborne contamination that contains alkyl chains. Our results also suggest that the wetting aging effect might be universal to a wide range of 2D materials.
