摘要
Graphene has received increased attention recently owing to its wide range of significant applications.Graphene is comprised of planar sheets of carbon atoms arranged in six-membered ring networks(Fig.1a).An atomically thin sheet of this substance can be regarded as molecular entity,in which nanometer-scale corrugations and defects create different physical and chemical environments.Knowledge about how these sheets interact with solvent molecules and how the defects govern these interactions is a critical component of understanding and predicting the liquid-phase chemistry of graphene.Contact angle measurements have been typically utilized to gain macroscopic information about interfacial interactions occurring between water and graphene.Owing to its one carbon atom thickness,the top single-layer of graphene is wetting transparent to the underlying substrates[1,2].The surface hydrophobicity of graphene can be induced by adsorption of airborne pollutants(e.g.,hydrocarbons)[3].In addition,graphenebased interfacial materials having either superhydrophobicity or superhydrophilicity have been developed.
