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 foam material is provided that is formed from a body of silicone having a cellular structure formed by a plurality of interconnected voids. The voids have a relatively high volume of between about 0.06545 to about 268.0832 mm 3 and more typically about 65.45 to about 179.5948 mm 3 . The foam material displays unique tactile properties.

Abstract:
PROBLEM TO BE SOLVED: To provide a porous oil retainer made of a resin impregnated with a lubricating oil that has an excellent efficiency for use in the lubricating oil and high mechanical strength, and permits the resin and the lubricating oil to be combined corresponding to usage and specifications, and its preparation method. SOLUTION: This oil retainer made of the resin is formed by impregnating the oil in a porous material made of the resin having open pores on its surface. The open pores is formed via steps of making a molded product by using the resin and a pore forming material, dissolving the pore forming material thereafter and extracting a part of the pore forming material from the molded product using a solvent to which the resin is insoluble. Open porosity is ≤30%. COPYRIGHT: (C)2006,JPO&NCIPI
