Resumen:
The capillary flow in nanoporous anodic alumina membranes is studied by an optical method. The experiments consist in measurements of reflectance variations in time produced by the change in the optical path as a consequence of liquid imbibition in the porous membranes. A fluid dynamic model based on classical fluid mechanics is proposed to describe the liquid penetration in the porous matrix and a simple optical scheme is used to analyze the interference pattern. Both the physical properties of the fluid and the main morphological characteristics of the porous matrix can be successfully evaluated by this model.
