Interfacial tension and wettability of water solution on hydrophilic and hydrophobic surfaces

It is well known that the surface tension of water is reduced by surfactants. For interfacial tension, however, the spatial arrangement of surfactants is affected by the opposing solid or liquid against water and the charge and activity of surfactants. Here, using atomistic and coarse-grained molecular dynamics simulations, we study the interfacial tension and wettability of water containing amphiphilic molecules, charged surfactants and active surfactants against hydrophilic and hydrophobic surfaces. The research will shed light on the adhesion of droplets, such as virus-containing aerosol, on different types of surfaces.
