Abstract
Wettability of surfaces is a significant factor affecting properties like water dispersion, spreading, evaporation, dissociation and etc. Surface wettability and wetting behavior of a surface are a subject of broad interest, there is then a great interest to understand better liquid–solid interfaces and water contact angle, in addition to the potential applications in micro- and nano fluidics. This subject is interesting as the growing attractions on the wetting and dynamical properties of water on 2D materials. Also, two clearly defined rigid water layers on solid surfaces are a well-known phenomenon and have been described on several surfaces. Detailed molecular dynamic simulation studies on the origin of this phenomenon are also of general interest. In this current review, recent attempts concerning to the wettability of graphene, graphene oxide and also some metal surfaces obtained by theoretical are presented. Their result contents, therefore, is of interest in order to understand the behavior of water nano-droplets when physisorbed on different substrates. The information is relevant for experimental teams working in this subject, with application in areas as catalysis, friction, surface chemistry, adsorption, etc.
