Abstract
A surface of a support comprising through micropassages is brought into contact with an aqueous solution comprising a plurality of particles in suspension and a pad. A pressure perpendicular to the plane of the support, between the pad and the surface of the support, and a relative movement of the pad and of the surface in a direction parallel to the plane of the support are applied. At least one particle is thus introduced in each microgap to form a porous material therein.
