Percolation, depinning, and avalanches in capillary condensation of gases in disordered porous solids
arXiv:cond-mat/0206108 · doi:10.1209/epl/i2003-00407-y
Abstract
We propose a comprehensive theoretical description of hysteresis in capillary condensation of gases in mesoporous disordered materials. Applying mean-field density functional theory to a coarse-grained lattice-gas model, we show that the morphology of the hysteresis loops is influenced by out-of-equilibrium transitions that are different on filling and on draining. In particular, desorption may be associated to a depinning process and be percolation-like without explicit pore-blocking effects.
