Abstract: Polymeric aerogels, articles made from the polymeric aerogels and methods of making the polymeric aerogels are provided. The aerogels are made e.g. from crosslinkable monomers such as isocyanate monomers or phenolic monomers and a filler comprising crosslinkable hydroxyl groups. The filler may be natural (e.g. wood flour) or synthetic. The aerogels and products made therefrom exhibit low thermal conductivity and are mechanically strong. Due to their physical properties, these materials are used as e.g. building envelope components, such as walls, roofs and frames, to improve the thermal performance thereof, and may be used in a variety of other applications such as sound and insulation barriers in mechanical equipment, cryogenic containers, etc.

Abstract: Drying polar solvents which do not form hydrogen bonds with a wet gel or aerogel, or eutectics or solvent mixtures with the drying solvents, are utilized in a solvent exchange with wet gels used in the formation of aerogels. Preferably the drying solvents are non-polar solvents. The drying solvent or solvent mixtures results in profoundly less shrinkage, thereby allowing for the production of aerogels of preferred materials properties.

Abstract: A method of synthesizing aerogels and cross-linked aerogels are described that incorporate freeze-drying in lieu of supercritical solvent drying. Advantages over supercritical drying include a reduction in hazard risks posed by drying at supercritical conditions as well as the ability to up-scale the process to accommodate large pieces of material without introducing risk. In addition, inexpensive and more sophisticated mold technologies, which are not impervious to supercritical conditions, can be used to produce aerogel materials according to the freeze-drying method of the invention. This introduces a level of freedom never before available for the production of aerogel components.

Abstract: An open cell foam, and particularly aerogels or other foams, having an inorganic, hydraded phase change material (PCM) embedded within pores or cells or a network within the foam have fire retardant, fire resistant and thermal insulating properties. These composite materials are preferably monolithic in character, and are mechanically robust allowing for example the attachment of nails or screws. With the PCM distributed throughout the open cell foam, the composite material has a wide array of applications including providing thermal, fire resistant, and fire retardant uses in battery containers, in automotives and other vehicles, etc.
