For understanding such complicated behavior of droplet, simple but fundamental consideration is very important. In the present study, wettability of a binary mixture droplet on low surface energy solid is experimentally and theoretically investigated. A simple theoretical model is applied to the droplet behavior considering a situation before and after touching the solid surface from a view point of thermodynamic surface energy. The model can explain the relationships among the contact angle (θ), surface energy of liquid (σlg) and the droplet radius (R).Read More
