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.

Abstract: The present invention describes various methods for manufacturing gel composite sheets using segmented fiber or foam reinforcements and gel precursors. Additionally, rigid panels manufactured from the resulting gel composites are also described. The gel composites are relatively flexible enough to be wound and when unwound, can be stretched flat and made into rigid panels using adhesives.

Abstract: The present invention relates to a process for preparing a porous material, at least comprising the steps of providing a mixture (I) comprising a water soluble polysaccharide, at least one compound suitable to react as cross-linker for the polysaccharide or to release a cross-linker for the polysaccharide, and water, and preparing a gel (A) comprising exposing mixture (I) to carbon dioxide at a pressure in the range of from 20 to 100 bar for a time sufficient to form a gel (A), and depressurizing the gel (A). Gel (A) subsequently is exposed to a water miscible solvent (L) to obtain a gel (B), which is dried. The invention further relates to the porous materials which can be obtained in this way and the use of the porous materials as thermal insulation material, for cosmetic applications, for biomedical applications or for pharmaceutical applications.
