Infiltration Non-wetting Liquids into Nanoporous Media at Different Initial Degree of Filling

The paper presents a physical model can qualitatively explain the observed experimental dependencies of reducing the pressure of the second and subsequent filling of partially filled porous medium. The model is based on an approach based on the fact that the pores in the porous medium is a chaotically arranged spherically shaped voids. If liquid is leaking out of such an environment is the formation of clusters associated with a liquid meniscus at the interface with air. Upon subsequent filling of the disappearance of the menisci is energetically favorable process that leads to a reduction in filling pressure.
