Abstract: The present invention is a method of producing porous beads, which comprises the steps of providing a first liquid phase comprising a bead matrix material and essentially edgy templating particle(s), said particle(s) being treated with a surface modifying agent; providing a second liquid phase which is immiscible with the first liquid phase; contacting the first phase and the second phase under conditions resulting in an emulsion of droplets comprised of the first liquid phase dispersed in the continuous second liquid phase; transforming the droplets to mesoporous beads by solidification of the liquid; and removing the templating particle(s) from the beads without causing any essential change of the surrounding bead, whereby hierarchical networks of pores are provided in the beads.

Abstract: A method for forming an open cell texturized surface in a silicone elastomer layer of a breast implant, or other medical implant, is created by forming a layer of uncured silicone elastomer, applying a coating of particles to the surface thereof, and curing the layer by heating it at an elevated temperature which also volatilizes the particles such that their constituent gases boil through the surface of the layer and create the texturing.

Abstract: A process for producing porous polymer material. The method combines a polymer and water-soluble granules to form a mixture. The mixture is placed into a mold; the surface of the polymer is dissolved to cause cohesion and form a polymer structure having water-soluble granules dispersed within, and water is introduced into the inner part of the polymer structure so that the polymer is solidified and water-soluble granules are washed out to obtain a porous polymer material. According to the invention, single or multiple layers of porous polymer material with different apertures, porosities, or made with different materials, are obtained by combining different polymer materials and water-soluble granules having different particle sizes in different weight ratios.
