A possible hydrodynamic origin of the forces of hydrophobic attraction

It is suggested that the large attractive force between two hydrophobized surfaces immersed in water may have a hydrodynamic origin. This force may be due (1) to the instability of the planar interfaces between the water layer and the hydrophobic surfaces caused by the incompatibility between the tw...

Description
Summary:It is suggested that the large attractive force between two hydrophobized surfaces immersed in water may have a hydrodynamic origin. This force may be due (1) to the instability of the planar interfaces between the water layer and the hydrophobic surfaces caused by the incompatibility between the two, and (2) to the fact that the fluctuations of the two water interfaces generated by the instability are hydrodynamically correlated. A simple, approximate model is suggested, on the basis of which an equation for the force is derived.
