Physical model of porous medium with controlled permeability based on pdms

For filtration studies in a wide range of permeability a model of porous medium was used a porous cross-linked polymer polydimethylsiloxane. Its permeability and porosity is well-controlled in a range of 0.1-30 000 mD. In the work several samples of porous media with various permeability are presented. Obtained minimal relative permeability for water is order of 1 mD in the porous medium model.
