摘要： Prepare a polymeric nanofoam using a continuous extrusion process by providing a polymer melt of a polymer composition in an extruder, introducing carbon dioxide to a concentration above the solubility in the polymer melt, cooling the polymer melt without increasing the pressure to achieve conditions where all of the carbon dioxide is soluble in the polymer composition and then extruding the polymer composition and carbon dioxide mixture through an extrusion die so as to experience a pressure drop of at least five MegaPascals at a rate of at least ten MegaPascals per second and allowing the polymer composition to expand into a polymeric nanofoam.

摘要： An article contains inorganic nanoporous particles bound together by water dispersible polyurethane, the article having 75 volume-percent or more inorganic nanoporous particles based on total article volume and having a density of 0.14 grams per cubic centimeter or less and a thermal conductivity of 25 milliWatts per meter*Kelvin or less and having a thickness of at least 0.5 centimeters. A process for preparing such an article includes dispersing inorganic nanoporous particles into an aqueous dispersion of dispersible polyurethane to form a dispersion, casting the dispersion into a mold, and drying to form an article. A method for using such an article includes placing the article in a structure between two areas that can differ in temperature.
