Zheng L and Zhao Y
A facile, safe and low cost thermal approach was developed to regulate wettability of graphene-based surfaces from superhydrophilicity to superhydrophobicity, which promises mass production on surface technology in various industrial applications. The long-lasting stable superhydrophobicity was attained by hydrogenating graphene with chem-absorbed functional groups. Meanwhile, the approach paves the way for producing fully hydrogenated graphene, which is an entirely novel material called graphene.
