✦ Synopsis

We have generalized the hydration force theory by including a surface contribution to the total free energy that depends on the normal component of the order parameter at the surface. Furthermore we have investigated the characteristics of the repulsive pressure as a function of intersurface separation in the case where surface free energy exhibits multiple minima, correspondingto different surface ordering states, and allows transitions between them. We have shown that surface ordering transitions are mirrored as breaks in the hydration force curve
