TL;DR: In this article, the authors studied the mechanism by which clumps of some powdered materials break up and disperse on a liquid surface to form a monolayer of particles, and they showed that when particles on its outer periphery come in contact with the liquid surface they are pulled into the interface by the vertical component of capillary force overcoming the cohesive forces which keep them attached, and then these particles move away from the clump.

Abstract: Abstract We have recently shown that the capillarity-based process for self-assembling particle monolayers on fluid–liquid interfaces can be improved by applying an electric field in the direction normal to the interface. In this paper, we present a technique for freezing these monolayers onto the surface of a flexible thin film. The technique involves assembling the monolayer on the interface between a UV-curable resin and a fluid which can be air or another liquid, and then curing the resin by applying UV light. The monolayer becomes embedded on the surface of the solidified resin film.
