Effects of confinement on self-assembling systems

Abstract
Systems in which particles can self-assemble into mono- or bilayers can form variety of stable and metastable structures on a nanometer length scale. For this reason confinement has a particularly strong effect on such systems. We discuss in some detail effects of confinement on lamellar and cubic phases with double-diamond structure. Structural deformations in slit geometry are described for large and small unit cells of the structure (in units of the thickness of the monolayer) and for various strengths of interactions with the confining surfaces. We show how the structural changes of the confined fluid are reflected in the measurable solvation force between the confining walls.
