Abstract
A discussion about Fakir droplets is presented. The water droplets stick to the pane rather than sliding down, due to small defects that are always present on the surface of a solid and that pin the leading edge of a downward moving drop. It is found that water drop wetting a normal surface forms a low internal contact angle while non-wetting, quasi-spherical drop forms a high internal contact angle on a superhydrophobic surface.
