文摘The wetting phenomenon of water droplets coexisting with the ordered water monolayer termed an unexpected phenomenon of“water that does not wet a water monolayer”at room temperature has been found on several solid surfaces.Although the hydrogen bond saturation inside the monolayer can qualitatively describe this phenomenon,whether the Young-Dupre equation still holds under this unconventional wetting framework is still not answered.In this work,we have´calculated the contact angle values of the droplets as well as the work of adhesion between the droplets and the monolayer based on an extended phantom-wall method.The results show that similar to the conventional solid-liquid interface,classical Young-Dupre equation is also applicable for the interface of liquid water and ordered water monolayer.
